There is a red notification bubble which appears to the top right of my Avatar, which shows the number of outstanding notifications that I need to look at, but can show an incorrect count of unread posts.
If I read each of the new replies to topics by clicking the relevant links within received emails, and then navigate to the notifications page, the topics which I have just read are still marked as not read, and the notification bubble number reflects those incorrectly outstanding unread items.
If I then click on one of the highlighted (supposedly) unread posts, then all the notifications get recalculated to reflect the true state of read/unread, and the red bubble updates with the correct figure.
The issue is that the status's are not correctly calculated when you first visit the page, and only updates when you perform some action within that page.
