i think the race problem occured when i made a new race instead of copying a default race.
The geck always lists a bunch of people in new races until you've made one or two custom NPCs in that race, have saved the esp, and have restarted the geck.... then only your custom ones will show. Those fake listings can happen with both new races and copied races, but it's only a geck display thing as the NPCs listed are not actually assigned to the new race (open them to verify). I think the geck just needs some names present to complete the new race form.
when i was looking around the forum i found something about turning .esp into .esm, the strange thing is that i have other mods in progress which don't have this problem, i wonder if it could be a save corruption problem with the G.E.C.K.?
It's a bug introduced with the last update for the game that never got fixed, and it goes hand-in-hand with 2 other NPC skin display issues. The fixes for all 3 are setting the npc to 'can be all races', setting the bLoadEGMfacegenFile (can't remeber exactly what it's name is) to true in the fallout.ini, and converting esp's that use custom npc skin tones to .esm.
Sorry, I'd look that one up for you but I don't have the game installed... I need the harddrive space because New Vegas is released tomorrow !
