Hmm, puzzling indeed. Usually when I have a levequest as part of the initial main Q, it still appears underneath the active quests in the journal list. I can't screenshot to show you unfortunately as I've done them all, but it's definitely always there.
I'd hazard a guess to say it's a bug as well. Have you tried setting the main Q for the leves as your priority and cancelling the others, it might just trigger something to show up?
