DAZ Studio 4.15 Metallic Flakes Goofiness?

Hey all, it's been a couple of years since I was last in DAZ Studio land, and I just downloaded the latest version 4.15. I then opened an old scene with a G3 character and all was well with one exception:
The original face and body shaders had a light dusting of gold metallic flakes applied. But when I rendered in the new version the body was fine, but the face was one big shiny gold orb. It's like someone had cranked the weight/whatever of the metallic flakes shader to max or something. But just on the face.
Did I miss something? Is there a magic button I need to push to make the old shader settings work with the never version(s)?
Can't imagine I would have saved the old scene with goofy face shaders like that....
Thanks.
