Duplicate artists

For multiple artists there are duplicates, one being the actual artist and another, exactly the same with a popularity of -0.1 and the problem is that they collect minutes separately. For example, there’s this problem with Radiohead and for the actual band I have a few thousand minutes but I have hundreds more minutes on the duplicate artist. Because of this; in the past 4 weeks I’ve been listening to Weird Fishes / Arpeggi a lot so it appears twice on my stats, both with different minutes corresponding to which artist released it (real or duplicate). This is annoying because it messes up my total minutes for that song, for the artist, and for the album. Another artist I noticed this for was Kendrick Lamar and I’m pretty sure there’s others too. I imagine this is a bug, if not then I don’t understand why it’s a feature
