Playback History Display Bug

I am a user who uses Spotify, Apple Music, and Stats.fm in Japanese.

When using both Spotify and Apple Music, even if I play songs by the same artist on both apps, the playback history under the ''Top'' tab shows them as different artists.

Specifically, the same artist appears twice: once with the Japanese katakana spelling and once with the English spelling. It seems that playback history from Spotify is assigned to the katakana version, while history from Apple Music goes to the English version.

I would like this bug to be fixed, or for a feature to be added that merges these two different artists or songs into a single entry.
