The number beside review is not going away, but there are no available reviews. I just got 2000 rep points. I am not going to correct spelling or edit unless it is to help the OP. What am I misunderstanding?
You can only contribute a fraction of what's needed to get the item off the review queue. Many review 'tasks' take more than one vote to be cleared, for example, it takes five votes from five different users to close (or reopen) a question. The red review notice numeral will not change on your vote unless you are casting the fifth vote.
So... it takes a village to clear the queues.
The fact that your queues are empty means you've done all you can do already on the posts in the queues. Good job!
