Review notification doesn't clear for approved user

Hi all!

We encountered a strange issue with notification for a user’s review.

So we set that every user needs to be approved. Recently we approved one, he even posted one post on forums but this notification still points that we need to approve the same user. How can we clear this?

Other users that registered before or after this one are approved, review notification clears for them, but only this user keeps in the queue.

Any ideas?
