Some of my top tracks (songs off folklore) are completely different songs but an artist I've never heard of

I checked the leaderboard too - it definitely is a taylor swift song but it's seems the data from the song is wrong? It’s making it a completely different song. I first noticed this maybe 5 days ago? I assumed it would fix itself and it was a glitch but I think something’s going wrong with data? It’s number 4 and 6, I don't know if it’s anywhere else though
