First, know that I discovered this on the game dev SE, but i think it might apply to many SE sites that don't have a ton of questions.
On the review tab I noticed the total next to each option to review. Then when you actually click on one, surprisingly it would be empty.
It took me a few moments to figure out that this was because it was on the day setting. To actual match the total you would have to click the "all" button. Essentially what I am saying is that this behavior is unexpected and maybe a more intuitive way of doing it would be to send the user to the page with "all" selected, therefor you wouldn't default them to seeing 0 posts.
