How can I burn my itunes purchased songs to a disc now that itunes is a part of Apple Music?

I did put my tracks into the playlist, but the Burn Playlist to disc was very light and would not work when clicked. Other playlists that I created before there was Apple Music, the Burn Playlist to Disc worked, as it always did. I went back to make certain that every song on my new playlist was a song I purchased on iTunes, and they were, but, Burn Playlist to Disc still didn't work.
