Black eyes after Face Transfer

Voxxa

I think FaceTransfer is super fun. You get models with more of a personality as a result. Just love it. Have made several successful projects using FaceTransfer. But yesterday something went terribly wrong. One of my Face Transfer projects resulted in the model having black eyes. Just as she would've starred in the TV-series Supernatural portraying a demon.
Now, I've checked the forum for soultions, but nothing of the answers and solution really fits to this problem. I've tried to add eyes from other PA's but to no avail. Tried to loead another Genesis 8 Female, resulting in the same black eyes for her. Also tried with Outrider42's soluttion Eye Moisture Pushout in DAZ Studio 4.20. It wasn't even visible in Parameters->Actors->Head->Face. At least not in 4.20.

The model I tried to imitate is the supermodel Anne Vyalitsyna. I came pretty close except for the black demon eyes. OK, tried to load a standard Genesis 8 Female to see if the results would be the same. And YES it did result in the same eyes.

What's going on here???
