Spotify download

Hi, I have R4 Evangelion. Recently I upgraded my microsd card to 1Tb Sandisk Extreme Pro, mainly due to the fact that Spotify became too slow with Lossless downloads the previous card (Sandisk Extreme 512Gb).

However, I noticed that while I download playlists/albums/songs for offline listening on the new card, system creates additional files in the Other Apps category. The more I download the more grows Other Apps. This is not the case with iOS version.

Any idea why does this happen?

Thank you for your replies.
