Episode #3.4 - S3-E4
Other mistake: Twice in the episode Fidel gets from the computer a fingerprint match for Adam Frost. The date of the sample is February 10th, which not only is inconsistent with the supposed timeline of the episode (the security camera puts the murder on March 7th, and the previous episode was set in the fourth week of March as per the gigolo's appointment schedule). but also differs from Natasha's fingerprint date, February 9th. The murder was discovered in the morning, so the victim's prints have been taken the same day as the suspects'.
Episode #3.4 - S3-E4
Other mistake: The phone records Fidel shows are of February, with Valentine's day being the latest entry. It is inconsistent with practically any other inconsistent bit of the episode (bank statements in February listed as 3 months prior, security camera of March, fingerprint file dated February 9th).

Episode #3.4 - S3-E4
Other mistake: When Dwayne stalks Simone, his sidecar is smack in the middle of the driveway when she approaches; he drives away towards the left but he is then lurking on the right side of the road as she drives off. All of that with his front light on. Not even a blind person could Miss it, and he'd have to swerve wildly to get in that sort of position. (00:28:10)
Episode #3.4 - S3-E4
Other mistake: Humph points out a suspiciously large cash transfer that happened 'three months ago'. On the bank statement, the transfer is shown as happening on Feb 3, so we should be around May. The security footage Dwayne reviews established that the murder happened on the 7th of March. (00:22:00)
Episode #3.4 - S3-E4
Other mistake: When Camille checks out Natasha's bank statement (a picture of it, which is kinda odd as you'd expect another file format), it contains amongst many other payments also a cash transfer to Paul Bevans for €10,000, but the subtotals do not reflect that at all (from over 18k Euros goes to 12k). There is also the not negligible detail that her name is misspelled in her own bank account; she is "Natasha Thiebert" but the statement spells it "Tieebert." (00:22:05)
Answer: There's probably no particular reason. Sets and props on long-running TV shows often change as needed and for various reasons throughout a series run.
