So hey I am working on a Homebrew race and want them to be able to choose 2 martial weapons to be proficient in. I am usually quite proficient (haha I'm not funny) at this but for some reason it's not working, help. 

Modifier: Proficiency->Subtype: Choose a Martial Weapon

(Do it twice.) Then, as always, save the modifiers, then re-save the racial trait, then re-save the entire race, then wait at least 20 mins for it to push through to the character sheet:

Thanks, that's what I was doin but now suddenly it works. Probably a glitch earlier, anyways thanks.
