If you type /console reloadui then open the reputation UI window. There's little or no factions listed.
And I don't think this is the only issue UI-reloading is causing. Just the other night I was in Alterac Valley.. And after doing a little /console reloadui in there. I noticed after a while that I could not attack a single NPC character in the zone. My little gnome dude would say, "I can't attack that target" whenever I tried.
