Deliberate mistake: When Wonder Woman is bouncing around in the padded room, there's one part where you can tell the stunt double is not Wonder Woman.
The Man Who Wouldn't Tell - S2-E20
Deliberate mistake: In the laundry warehouse, Wonder Woman launches a man up to a beam. Due to his unnatural movements, one can easily tell that the scene is played backwards and he really was falling down.

The Man Who Wouldn't Tell - S2-E20
Deliberate mistake: In order to knock down Ted at the laundry place, Diana opens a bag filled with clothes that are supposed to fall on him. The bag is too low plus the actor is away from the bag, so when she opens the bag he crouches, then grabs the clothes and pours them on top of him and falls down. It's all very lame.
Disco Devil - S3-E5
Deliberate mistake: When Diana escapes from the attacker, the coffee table in the living room is away from the couch. When she comes back, it's next to the couch (to give more space and allow for the action scene to take place).
Phantom of the Roller Coaster: Part 2 - S3-E24
Deliberate mistake: When Wonder Woman jumps from the tall building to catch Fynch, she is falling on her back (for a safety landing on an airbag or similar). However, shot cuts, and she is suddenly jumping ahead towards Fynch.
