[Help] Need help with morph

I encountered a problem when I was trying to convert the head shape of CC Jynksie for Genesis 9 to genesis 8: when I apply the morph, the eyes follow the morph, but the iris part is deformed. I tried both by making a fitsuit of genesis 8 and applying a full morph, including of the body, with the genesis 9 figure; the second time with the fitsuit of genesis 8, but leaving the genesis 9 figure with the genesis 8 clone applied, applying the morph of the head, but as a result it was noticeable that on the fitsuit the iris part was deformed and was a bit more visible.

Does anyone know how I can solve it?
