Hi Zachary I think it's an issue with the OI "Trigger Press". It seems to happen when players you want to press have the ball, the entire back line will step up to attempt to press them.
pkm attached, incident at 4min mark, my entire defensive line charges straight ahead when Ofori has the ball, and I have asked my team to trigger the press when he has the ball
Another example for the Paderborn goal (45+2), defenders seemingly just wandering off up the pitch. I suppose that one you could argue my defenders are trying to play their forwards offside
