Kraken Tooth Daily Quest

Hey everyone,
basicly just started new on the server and got right away to work on the argent tournament dailies.

Yesterday i finally managed to get the last Faction Capital to exalted and finish the dailies there to unlock the title 'Crusader' and the last crusader dailies in the main tent.
Over the past few weeks i already picked up some 'Kraken Tooth' whille doing some of the dailies and i wasnt able to accept the quest, since i didnt unlock the right achievement yet.
However today i got the 'Get Kraken' quest, killed him, got the tooth but it still says i don't meet the requirements for the quest. Am I missing something or is there a known bug? I basicly unlocked everything at the argent tournament, except the achievements for quel'delar, Pony Up! and Tilted!

/edit: guess i figured it out. Could accept it after turning in the "Get Kraken" daily
