Importing/paste copies the main layer

I was making a small animation on Animate and whenever I add new objects to the stage, it makes a copy of the main layer. Thing is, it cannot be interacted with, if I move the item that I can touch, the other will move with it, then center. I made a copy of the item I added to the stage, the problem went away. But as I edited it, it was disappearing into the project. And the frames before that were effected as if I somehow took an eraser to all of them. Then I try to replicate those frames, and then the image comes back again.
