grease pencil jaw randomly broke? need help fixing

I'm making a animation and it was fine until i started working on the mouth and lip syncing. my jaw and mouth are on different layers so I'm really confused on how this happened. also its not weight painting since i checked that and when i tried to move the jaw back it wouldn't let me move it? like it would go anywhere but where the jaw is and when i fixed it at first it broke again the second i started playing the animation. last image is what the jaw is supposed to look like first 2 are what it looks like right now
