I have the same problem. It's been reported on the bugs forum a few times, and supposedly the information is passed onto the devs. All I've ever seen it get is a canned response from a community manager. But, hey, maybe you should post it there, anyway. The more complaints they get, the better.

Also, logging out does not always fix the problem for me. Sometimes it even just fixes itself while I'm logged in. I have no idea what specifically causes it or what fixes it. It seems very random.
