software Premiere Pro to Audition

Hello everyone! I'm working on my documentary and finished the video editing process. Now I need to smooth out dialogues and music in Audition. My Premiere Pro project is divided in folders. Each folder has a sub-folder for it's corresponding audio. When I open the premiere project in audition, it's shows me those exact folders but they're all empty apart from one. One of the sequences I can select is the entire project and selecting it opens a single audio file so I cannot edit the tracks individually. It seems as if I did something wrong with the folders. What did I mess up in my project?? Thank you all in advance
