Duplicate Versions of the same album

I migrated stats.fm this week, but to my surprise, I've noticed that the numbers are a bit more inflated compared to http://last.fm. The biggest problem for me is this inconvenience of duplicate versions of Ceremonials. I've been listening to the exact same version on Spotify forever (https://open.spotify.com/intl-pt/album/19J2iqK89BCrNG4El2FRi5?si=NHeRULYgTu-zIH149J8GpA), but to my surprise, http://stats.fm is reading it as if there are two versions, which has been causing me this trouble. I'm trying to fix it, but I don't know how.
