DNxHD audio levels??

(for preface, i don't know a lot about the codec i'm working with. i just settled on it for the bitrates and quaity.)

needing some help here, so i'm working on a music video project, deliverable to disc. and i wanted to have an archive to call back later on if i want to. figured the best option would be to export to dnxhd. looks and sounds great. but the audio levels when re-imported to premiere are clipping?

so intially during the edit,i ran the audio through audition to add a very light multi-band compression to ensure its averaging at -.1db. when i import into premier it sits at -.1db. great.

when i export to h264/pcm for disc authoring, and import the wav into audition to inspect, it sits at -.1db. great.

when i import that exported stereo wav into premiere, it sits at -.1db. great.

when i export as avid .mxf and import that into audition to inspect, it sits at -.1db. great.

however, if i import the avid .mxf back into premier, the same file in audition that sits at -.1db is now at +2.4db clipping.

i'm assuming there's a setting in premiere that will lock this into place like it needs to be, because the files seem fine. it's just how premiere is reading them is wonky.

so the dnxhd file comes in as dual mono tracks it appears. but both tracks together form the stereo soundscape, but they are playing in mono because both track 1 and track 2 are playing in both fields. if i mix track 1 to -100 and track 2 to +100, the oevrall audio is now -3.5db. not -.1db like it should be. sure i can set the track mix to -100 for 1, +100 for 2 and the overall level to 3.0 to achive -.1db, but i feel like i shouldnt have to do that? it's just weird that the levels are fine in audition, but not in premiere because it's playing both mono tracks in both channels when one is left, and one is right.

so can someone help me make some sense out of this? or is this just the nature of working with a codec that outputs in dual mono-stereo (or whatver you would call this type of audio)?
