Keyframes not working, unable to move images.

Hey, so, I'm relativly new to animating and to Adobe Animate. I've been animating this longer sprite animation, and randomly during it, I insert a new keyframe and it's the color dark grey to show that it's empty. However, when I add in the image for the keyframe (in this instance, Piccolo is the image here) it stays dark grey when it should normally turn a lighter grey since there's an image in it. So, that's weird, but then it locks Piccolo in one spot and makes it impossible to move him, anytime I try it just snaps him back to the center position. What's up with this? Anyone know how to fix this?
