Object changes position in Edit mode

I have this problem with my character. If I go in to edit mode on any of his parts the object moves to right a little.
I guess this is a problem with alignment but I can’t figure it out.

Have you a frame on the object ?

No, I must’ve pressed somethig wrong but I have no idea what.
I can attach the file if that would help

Any Shape Keys on it?

Lots, Around 30 but only on the head. I have none on the arms and the other parts but in edit mode all of them switch to right.
I have to mention that all the parts are separate objects, not joined.
