SOLVED-Lip Surface Outline Visible on Default Mats for V8 & other G8F's

I can't post an image at the moment, but I've had a recurring issue of the outline around the Lip Surface being visible when using the default/plain lips materials. What settings can I adjust to remedy or mitigate this? It happens on Victoria 8 and some other skins I've tried.

I'm using G8F in DS 4.9 on Windows 10. Help!

I had added some displacement to the lips and changed the Face and Lips Normals settings; so, I just went back to the stock settings.
