Argent Tournament Factions

I have already finnished 2 out of 5 faction dailies at argent tournamet..so that means i'm the champion of 2 alliance factions...but i have a problem there...it seems that i cant start the quest for the 3rd one...only quests i have there are those that give me champion seals..and since i became a champion of ironforge every couple of hours i get the quest "A Champion Rises" from Lana Stouthammer and "A Valiant Of Ironforge" from Arcanist Taelis and i can complete them every time...anyone out there who can tell me is this some kind of bug that everyone has or just me?
