First of all, I apologize for posting a screenshot from Stack Overflow in Russian. If you have the same situation, you can place English version here.
My low quality queue is empty (zero items), but popup menu for low quality posts queue has red lamp.
Before removing counter from popup I have seen
0 and never clicked on the item with zero count. Now I see red - going in and here is nothing to review.
Is it behavior by (new) design or some kind of bug?
A similar situation happened for close vote queue for another user, described on ruSO.meta. He has more items skipped during review, but lamp is red and queue is empty like in my case.
