Why can are songs that I purchased showing up as Apple Music files?

I’ve recently tried to burn a playlist of songs onto a CD. All of the songs that I am trying to burn are purchased and downloaded into my iTunes library. However, I received alerts that many of the songs could not be burned into the disc because they are Apple Music files. I am an Apple Music user, but I bought these songs (they show up in my purchases history). I’d really like to include them on my CD, but I am not sure how to switch them from showing up as an Apple Music file to a purchased song.

Any suggestions? Thanks for all help!
