[SOLVED]Object pushing other objects in weird ways, enemies teletransportation and weird jitter of enemies

I dont have a better way to explain this so here is a video of what im trying to fix.
Why this happens? The three enemies at the top are just a copy + paste of the three enemies at the bottom, so… Why this weird thing happens just on the enemies that are at the top and not on the original enemies?
[Uploading the video, please wait]
Edit: I just started recording and the enemies worked fine. This is insane. Gdevelop is coded in a way that when you start recording? Because It seems like that.
Anyways, thx for your help in the past, and sorry for my crappy english
