Levels are higher and compression not working when i export multitrack from Audition to Premiere Pro

So I do some post-production audio work on short documentaries that are edited in Premiere Pro.  I usually send the audio from Premiere to Audition to fine-tune it, you know clean up pops, some light compression, noise reduction, etc.  Then I send it back to Premiere as individual stem tracks, combine it with the visuals and export.  Right now when the multitrack is exported, the levels for the stems are much louder and it looks like the compression that I added to the master track in Adobe Audition isn't working.  Does anyone know what's up?
