search field within dropdown

i'm sure this is just a setting somewhere, but i'm having trouble finding it. when i'm in a pivot table, and adjusting the report filter, a drop-down list with all my options appear. i remember when working on other versions of excel there was a search box at the top of this drop-down box. i would be able to type in a portion of what i was looking for, and return only the fields that have what i typed in. the version i'm working on now does not have that "search box".

any help on how i might be able to turn on that setting? much appreciated.

after i sent out this original request, i thought it might be best exampled with a picture. attached is a screen grab i took to show my drop down box, and where the search box should be. does this help at all??

judging from the number of visits, and the lack of response, i figured this might still be confusing some people...or i'm just doing a horrible job of explaining it. i was able to grab a screen shot of my friend's computer with the search box i speak of. please take a look and compare this to the previous image i attached. how can i get this search box!?!

thanks everyone.
