Save and Export Buttons Greyed Out

Hi everyone,

I would really appreciate any help with a matter. I'm editing a project in Audition and I was just command S-ing when I noticed it didn't lead to any saving. Then I checked the file bar and all three save buttons were greyed out. Then tried to export to save my progress and the export multitrack is greyed out. I tried finding similar problems but all the results didn't solve my problem. Most were solved by the output not being in Mix but all of my outputs are in Mix. The closest problem I saw mentioned was that I had two sesx files with the same name, but I have no idea if that is the problem or how to change the name, as I tried changing the name of the original file, but it didn't change it in Audition.

I'm linking two images of my project and the greyed out buttons. Any and all help would be amazing! Thank you.
