my lobby/drop music set to "random" but always plays the "default" theme

I feel so cheap listening to the original theme over and over again on drop. The only way I can get it to not play the original theme is to set it to "random favorites" and that gets tiresome. 

Strangely enough this only happens in the ranked queue. It does play random themes in trio/duo queues but ranked always has it set to the original theme. please help.
