Search returning odd results

I don't know if it's my search query, or some historical thing but it seems that my searches come up with some odd results:

I search for

http://www.giantbomb.com/api/search/?api_key=API_KEY&query=Duke%20Nukem&format=json&field_list=name&resources=game

and I only get videos, but if I erase "&resources=game" I get games. Why would the resources filter using "game" only show videos?

Edit: It seems it remembers my last search and returns the same results even though my filters change.

Edit2: It will generate correct results if I modify the query.
