Remove Download Option Disappeared from Music App on iPhon

Something strange is happening with the Apple Music app on my iPhone. When I try to remove certain downloaded songs/albums to free up space (keeping them in my Apple Music cloud library but removing the downloaded file from my phone) the 'Remove Download' option is missing. I only have the option to 'Delete from Library,' which removes the songs completely. They disappear from all my devices. This only happens with certain songs/albums, seemingly at random. While it only happens with music I've downloaded from Apple, not ones I've uploaded from a CD or downloaded elsewhere, it doesn't happen with EVERY song or album I download from Apple. I've searched the community and found no real solve for the issue. Anybody have one? I use an iPhone 13 running iOS 16.6. Many thanks in advance.
