Help fixing GenX morph

Sonofbelmont

Hi
I've transferred a Girl4 morph on to Genesis using GenX however it has a few issues with the teeth and I'd like to fixe the problem. How would I go about doing this?
I thought it might be the same as replacing a auto generated morph and tried loading ony a corrected morph with the same name as the one I want to replace and chosing replace Deltas but the teeth just blow up an move outside of the mouth. I've already ruled out a problem with the morphs units but I did notice the original Gen x morph has has a few ERC Stuff attached to it.

Any help would be appreciated
Thanks
