Problems with converted legacy to G3F after restarting DAZ

RobertDy

I've been using darkhound1's legacy to G3F morph converter, https://www.deviantart.com/darkhound1/art/Legacy-to-Gen3-morph-converter-1-1-buy-it-here-589021408 , basically it lets you transfer your V4 shaping morphs to G3F. Never had any issues. Now this one suddenly came, the figure converted perfectly but after I closed and reopend DAZ, the legs now have a very weird shape. Like attached. I blacked out the privates. Anyone know what's going on and how to fix this?

EDIT: I think this might be caused by a clothing I autofitted using Wear Em All, it was for G2F fitted to this G3F model. I tried recreating the character step by step and closing and reopening DAZ in each step. The problem started after I fitted the clothing. What do I do to correct this?
