Playlist creation adding unavailable songs

When using the Spotify playlist creation feature, it appears that songs are being added that are unavailable on Spotify. For a specific example, it will add the song “Down In A Hole” from the album “Dirt” by Alice in Chains. However, the only available album on Spotify is the remastered version “Dirt (2022 Remaster)”. This is not consistent with any song from that album though. Certain songs will populate as expected.
