You did 12 beast quests because you started the first 6 before the reset, and when you finished you have 6 more due to the reset.
Even if you have 1 beast tribe quest that you haven't turned in, you will get no new allowance. After you turn in the last one, assuming you started that before the reset, then you will immediately get 6 new allowances.

So are you sure you have turned them all in? Go through the full list of your uncompleted quests again, there might be a beast quest from another beast tribe that you missed.
