Identical tracks counting for different streams

For some albums and singles, the single and album versions are identical but yet aren't considered the same on stats.fm. It seems the same when an album is reissued, as for example, Abracadabra is my most streamed song this year, but because the single/album/reissue are considered 3 separate tracks, it doesn't even come close on the app, when it's the same song, and Spotify itself treats it as such. For some songs I haven't had the problem, and I think the app should be more robust and capable of detecting when 2 tracks with the same name by the same artist are the same.
