AAF Media Folder disapears once AAF export is done

Exporting an AAF from my Premiere project. I started a new timeline that was simply just the audio. I deleted any video. I have exported a separate reference file for my sound mixer. My problem is when I go to export the AAF, a new folder with the AAF media is created, which is great, but then once the process is finished, this folder deletes. I have no idea how to stop it from doing this, and then I can't send the media to my sound mixer. I've tried every variable of the settings in the aaf dialogue box, and no matter what, the AAF Media folder keeps getting deleted as soon as the process is done. It's not in my trash, it's just gone.
