View Credits: Inconsistent

Just looked at a song‘s credits because it’s a cover (“Where there’s smoke there’s fire” by Black Keys) - I see a long list of musicians and then the songwriting credits to Willie Griffin. listen to the song, add to my library, go back to see that name again because I want to hear the original. now all the credits say is “Lossless” etc. No credits at all. anyone know what would trigger this?
