Question filtering isn't working as expected...but just for one user?

I'm trying to get to the bottom of some strange behavior in the f/q-a application on our site. We display the forums (named q-a and limited to questions and answers) on a page on many of our sites. The other day, I filtered the list of questions in the widget on that page to unanswered questions, and for some reason our instance seems to be "remembering" this choice for me as a user on every site in our instance now. It automatically filters for only unanswered questions, even though I've double-checked the widget and it's set to show all questions. I can manually change the filter to show all questions, but this doesn't "reset" the behavior for me across the site. Other users seem to see the widget list appropriately (they see all questions). 

I can't find any global setting for the forums application or any global user settings that would be making this happen. If anyone else has run into this and can help me, thank you in advance!
