I don't think this is a bug.
As far as I know, only answers (which are most commonly flagged as VLQ) can be voted-to-delete from the LQ review queue. Questions have to get closed, and eventually they will be deleted. I think the close option is the right option here.
You are not getting an item from the Close Review queue as you think you get, but from the Low Quality queue, it is just not very common to get a question there.
