As the picture illustrates the review count in the status bar showing review items when there are none.
When we rolled out the "pending reviews" indicator, we had to make an unfortunate concession to the fact that personalizing it for each user is too computationally expensive. The end result is that the number of pending reviews in the top bar is the total count of still active reviews in the system, including ones that are no longer available to you. (Plus some caching may be at play.)
We'd been thinking about ways to make this experience better, but I'm not sure what the status of that is right now.
