objects move when the first time when i flip them but only the first time? (video incl)

Hey, so one of the bugs (if it is a bug and i'm not doing something wrong) is that half the time i try to flip and objects(s) they jump half way across the screen. Some of this I can attribute to having some mark or dot I didn't notice that was way off center, but I also notice that some cleaned up symbols are doing the same thing and only on the first flip. Here is a video, can anyone explain this to me? (on a related topic i noticed that when i locked my characters arm layers as to only flip the torso, one of the arms stuck on and refused to let go of the torso. I have both arms parented to the torso and both arms locked so why does only 1 stick? Here's the vid.
