Imported stereo music file playing in one ear in podcast project

I imported a mono vocal file (recorded in audacity) into Audition. It was fine. I could hear it in both ears. I imported a stereo music file into Audition onto a second track, and I can only hear that music play in one ear. (left) 

I cannot figure out how to rectify this. Although I hear the voice just fine in both ears, the music "feels" disturbing since it's only coming through the left ear. 

I'm using a Focusrite usb audio interface; that's what I have my headphones plugged into. 

I originally recorded the voice in audacity because Audition was crashing every time I tried to record.. and I don't have time to technically sort that out.. so I'm only using Audition right now to edit the podcast (just adding music). I just need to know how to keep the stereo music audio file from only coming through one ear. Thank you in advance, and I apologize for my technical retardation. I'm no sound engineer 🙂
