Leaderboard Ranking is not working.

Hello Stats, I am someone who loves music and competition. That is why I downloaded this app. I have noticed an issue. When looking at leaderboards for artists, I see that the ranks are not changing even though people are out-streaming other users and have more listening minutes than them. They are still remaining in the same inaccurate rank. The same has been happening to me. I am in the top listeners list for an artist, and my rank is not going up. Is there a way this can be fixed?
