EDIT: Test it with a couple of my girls and didn't find such problem. Have you tried more girls than this one?
There is one thing, though: in all the animations made with gimmicks, you have to adjust them if your girl is not the exact size of the template, which is not always that easy. Have in mind that what is to be moved are the pistons and rotators that affect the body parts, not the body parts themselves, wich means that you have to find previously the appropiate gimmick to move. Further, move it carefully and, most important, cross your fingers and try one and another time until you get it.
