Continuity mistake: When Wallace is looking at the newborn replicant with his visual aids, in the shot where he says "A child can count to nine on fingers", the corner of the towel that the replicant was covering herself with is on the floor.

Continuity mistake: When Mariette is standing in the street with the two other replicants, there is a woman to the right of shot, wearing some sort of mask and goggles on her face.

Continuity mistake: When Deckard heads for his car after he is found, he runs into a room with his dog, locking the door. He and the dog then run towards the car, with the dog running ahead of him, but in the next shot, the dog is suddenly behind him. (01:58:35)
Continuity mistake: Whilst the giant Joi is chatting up K, there are streaks of wet blood shown going down his neck due to his injuries getting rained on.

Continuity mistake: Whilst K is being walked through the orphanage by Mister Cotton, he stops when he recognises an area from his dream. In a shot from behind him, he is shown turning his head to the left to look at the area, but when the camera cuts to a different angle of him, he is looking straight forward, and then turns his head to the left a second time. (01:09:00)
Continuity mistake: Whilst Luv is in a meeting with a buyer, she suddenly gets a message alert. She is holding a cup of tea in her right hand and holding a saucer in her left. She then lowers the cup back onto the saucer without taking her hand off it, but when the camera cuts to a wide shot of the room, both hands are suddenly touching the saucer. (00:30:40)
Continuity mistake: When Luv is first introduced, she is shown pouring tea into a cup placed on a saucer and then raises the saucer.

(00:30:30)
Continuity mistake: K gets into his car after taking out Sapper and picks up a police report card from the dashboard to fill out. Whilst the car voice is heard saying "Incoming LAPD re-codec hash", K picks up a pen and places his right hand over the front of the report. His fingers are placed flat on top of the card when he does so. But then it cuts to a close-up shot of the card, where his fingers are now curled and the side of his hand is placed against it. (00:10:35)
Continuity mistake: Just after K has finished scanning Sapper Morton's eye, he stands up and says "Please don't get up" to him.

Continuity mistake: When Mariette is with K in the replicant hideout just after he wakes up, there is a moment where Mariette is shown placing her hand on the side of K's face. It then cuts to a shot focusing on Mariette, where her hand has moved down to the side of his neck. (02:04:00)
Continuity mistake: When Luv swims back to the sinking car, the exterior shot shows her placing her left hand on a seat in front of her. The shot then cuts to inside the car, where it is now her right hand placed on a seat that is to her right. (02:24:00)
Continuity mistake: When K swims back to the sinking car to stop Luv and rescue Deckard, K grabs Luv and pushes her up against the ceiling. There is a shot outside of the car looking inside the car, where K has his hand around her neck and is holding onto the side of her face. It then cuts to Luv where K now has his hand entirely around her neck. (02:24:10)
Continuity mistake: When K and Deckard are standing outside Dr. Stelline's facility, Deckard asks K "who am I to you?" and K turns his head to face Deckard. The shot cuts to K, where his head is suddenly slanted at an angle. (02:29:15)
Continuity mistake: Just after Luv throws herself and K out of the car after he attempts to rescue Deckard, the two land in the water rising up against the sea wall. When Luv first kicks K, he is kneeling on the ground attempting to stand up. The shot then cuts to a different angle, where K is suddenly standing mostly upright. (02:22:20)
Continuity mistake: When Freysa is speaking with K, she raises his gun so that it is pointed at her. Just after she says "Dying for the right cause is the most human thing we can do", when the shot is on K, he lowers the gun slightly and it goes out of frame. It then cuts to a shot focusing on Freysa, where the position of the gun remains the same and doesn't change. The shot then cuts back to K at the same angle, where the gun is now visible at the the bottom of the frame, even though the gun didn't change position. (02:06:25)
Continuity mistake: When K looks over to notice Freysa and the other replicants approaching him, Mariette has her hand near K's neck with her finger against his face. The shot then cuts to angle behind K where her hand is now around his neck. (02:04:05)
Continuity mistake: In the replicant hideout, when Freysa is approaching K, the shot where Mariette tells K he can trust them, she has her hand around the back of his neck, but when the shot cuts to a different angle, her hand is suddenly near the front of his neck and moving away. (02:04:15)
Continuity mistake: K has a drink from his glass of whiskey, puts the glass back on the counter and places his hand on the counter. In the next shot, his hand is suddenly back on the glass. (01:52:20)
Continuity mistake: When Deckard asks K if he has a name, K lifts his glass an inch off the counter and tilts it towards him to look inside it. The shot cuts to a different angle where the glass is now lifted further off the table. (01:52:25)
Continuity mistake: In the shot of K and Deckard being blasted back by the missile, they are right next to each other when they are about to land. In the next shot, they are suddenly meters apart. The dog also reappears in between them when they land. (01:58:45)
Answer: The birth records were purposefully mixed to hide Ana Stelline (Rachael and Deckard's daughter). She was passed off as a boy and raised in the orphanage. K was given her memories because she secretly was giving replicants pleasant memories of her own. She is in a containment area because it is said she has an autoimmune disorder, but this is likely a ploy by the freedom fighters to keep anyone from examining her and discovering that she is at least part replicant.
