I think it’s because Spotify frequently includes the same song as being on multiple albums separately–for example, if a band has a greatest hits album, Spotify considers the greatest hits album as a different song, even though it’s identical to the song on the original album.
They could even just be loose singles that are different. My list looks like I have 3 duplicates of Cumbersome by Three Mary Six; they’re all actually different versions of the song but since 2 of them were single releases and didn’t have an original album, they use the same album artwork the studio version is from.
