The little orange counter in the top bar with the number of outstanding review tasks has been off for the last couple of days.
At least in my profile the actual number of tasks does not appear to correspond to the number of posts in any of the individual different review queues, nor does it match the total number of posts.
Am I overlooking a queue or something or is there a small bug somewhere?
This is by design, amongst other things it is most likely to be caching in action. See the linked question on mSE for some more details.
The count in the top bar is site-wide, and includes items which you may have already reviewed or skipped, both of which no longer appear for you in the individual queue counts.
There's also caching, but that only lasts a minute or so.
To see the full counts, visit /review while logged out (e.g. in an incognito window).
