Hello, I have a problem. For some reason, my shapes jump when I change frame 0 to frame 1. What could be the cause? There can't be keyframes in such a piece.
I think I found something similar from the answers, but they talked about the offset bone tool, which I have never used (NEVER), but for some reason this weird jump effect is there.

When this happened before, I didn't know how to fix the problem and simply deleted the shape and re-drew it. Now I'm a bit tired, but I really want to figure out what the problem is.
Please help me, I don't want to redo everything.
