I figured it out. I was switching files in and out of dropzones to create test renders for the client. These clips had audio and even after they were replaced with smaller clips, they were getting exported to the media folder along with the generator. I resolved it my going into the audio tab and deleting the unneeded audio. this freed them up for deletion when deleting unused media.

Thanks for the feedback, and I hope this helps someone in the future.
