Audio feed returned as video

[mxpv]

hey max

thanks for the service. need a little help.

i signed up for your patreon so i could download youtube playlists into audio podcasts (which allow me to open other apps while the podcast is playing)

i'm trying to take this playlist and turn it into an audio podcast feed, but no matter what i try to do, it ends up being a video podcast feed. so any time i close the podcast app, the podcast stops playing

any help much appreciated. thanks!
