Unable to download the 'Wish You Were Here 50 (Documentary Version)' from Apple Music on my Mac

Cannot download my Documentary from Apple Music. Purchased the New Pink Floyd album: "Wish You Were Here 50 (Documentary Version)." All of the songs download fine, but I get this message when I try to download the Documentary:

It seems odd that the one thing I cannot download is the very thing this version was named for. I have already troubleshot everything I can think of, and support could think of. Neither of us could figure out why it's doing this. I can watch the Doc Movie from the cloud, but I can't download it to my Mac. Does anyone know of a fix?
