Gray Face Bug After Editing NPC in CK

[theinfamousworld]

I'm sorry to make a post that I'm sure has been done hundreds of times, but I've hit a wall.

 

I am trying to modify some of the faces of Skyrim's vanilla NPCs. The issue is, any changes I make on the CK translate into a default brownish grayish face for the NPC that I've modified. Ctrl + F4 method of exporting face data appears to do nothing.

 

I tried a clean install, as well as loading literally every single plugin I play with into the CK just in case there was a dependency I wasn't aware of, but no dice.

 

Would greatly appreciate any help on this issue.
