Ranks Problem [Solved]

I have a HP roleplay site. In ranks administration, I changed 'Admin' to heads of house, and then I added other ranks, like prefect and student. But when I go to the user's profile to change their rank, in the little pop-up menu it only says heads of house. Did I do something wrong?

for all of you who dont know, hp = hairy potter

And now, for whoever isn't a head of house, where it usually says "no special rank assigned" it now automatically says Student, but it's still the same situation as above. =[

Oh, and it's Harry Potter, not Hairy Potter.

oh, oops

Never mind, I figured it out by myself. (It seems I always do.)
