Ok - for me the facial type change/rechange is working at first
but indeed after save and reload it´s same as before.
Only saving another facial type will hold - very weird

Maybe there is an influence as they are AI-Cards - I´ve heard that the newer mod versions sometimes doesn´t work no longer the same on AI or HS2 cards.
Anyway both characters are hybrid - body is Hanmen shader, face is default AIT Skin True.
You should have both the same shader to lower the colour difference.
I would give them a complete skin overhaul and save new.
