Lots of music in my library is now grey and "not available in my country", but yet they play if I go to the Apple Music page

Tried playing some music today and I noticed a lot of my music is now greyed out. Since I use Apple Music I assumed it was some licensing issue or whatever and that the songs are no longer available to stream. When I try to play them through my iPhone or iTunes libraries the songs are grey and I get the message that they're no longer available in my country, however, if I browse for those songs in Apple Music they are there and play fine. My problem is when I try to add those songs again to my library nothing happens. If I delete the greyed out song from my library and add the one that plays through Apple Music, it does NOT add to my library.
