symbol gets half white when im editing it and broken animation when copying to put in a animation

[thomas turbano]

i create a symbol and when press ctrl c to copy something it gets half white and dont get off the symbol, only if i go back to stage and go back to the symbol, its honestly so bad, so is with me copying the frames in the timeline, and when i put it into a symbol it comes totally broken, with no layer parenting settings and random tweening directions  the half white symbol
