Using EZDrummer MIDI in AD2 with SONAR

I figured out where to put my EZDrummer MIDI files so AD2 can find them, but I can't get AD2 to display all the files on its Beats page even after refreshing. Something about EZDrummer's naming conventions is confusing AD2 so only a fraction of the EZDrummer files show up.
 
I can get to the EZDrummer files using SONAR's media browser, but I'd like to be able to access them all directly through AD2. Has anybody else encountered this problem?
