"Reviews Pending Approval" Link is active, but no reviews pending... problem...

I made a test review on one of the sample database items, and I deleted the item without approving the review.

I noticed that when I added the review, the "Reviews Pending Approval" Link became active.

Now, the link is staying active no matter what, and I can't fix it since the pending review was deleted, along with the deleted item. When I go to the reviews pending page, it's empty--there's nothing there.

It seems there some database flag that got switched on which wont switch off...

Where/ how can I find the database entry to delete that will set things back to normal? (so that the pending review link is only active when there's actually a pending review).
