How to fix white bodies on non-caucasian npc in fallout new vegas

I recently started a new playthrough of Fallout New Vegas and decided to add a custom NPC. So I started up the G.E.C.K. and added a new NPC. I decided to make the NPC an AfricanAmerican. After doing some basic setup I placed the NPC somewere in Goodspring and test out what I had created so far (some basic dialog). However, the NPC turned up with a white body.

Since I ran a heavely modded game, including body replacers, I figured it might be a problem with Archive Invalidation, or one of the mods acting up. So I removed all mods, tried again, but that didn't fix it. I made sure I invalidated the archives (tried using FOMM, NMM, ArchiveInvalidatorValidated, manualy changing the INI's, etc.), but that did not work. I then decided to do a complete clean reinstall of the game (making sure the to remove the game folder so all mods where deleted as well), but that didn't help either.

Note that I do not refer to the pale faces glitch which is fixed by a INI setting. Note also that I did all INI fixes in all three INI files.

So I'm unsure how to continue on fixing the game and would welcome any advice!
