ultimate pose master for genesis 8 by v3digitimes not working correctly

I'm trying to hold the feet in place and move the genesis 8 body and it just doesn't seem to work; the legs go off in crazy directions. I've done this same exact thing with genesis 9 and it works great. I've attached a comparison of the same starting pose and then moving the full figure in the +y direction. I've choosen "adjust feet to stay on helpers".
