deleted streams

I almost every day check the songs i've been listening to lately, and yesterday it said i listened to 500 minutes of one artist and 111 minutes of another. today, it says 387 and 78 minutes respectively. why does this happen? i've been here a long time, but this app is full of bugs :(

i've also noticed that streams of my most listened-to artists of all time have been removed.

I hope you will offer some solution, although it seems you're not interested in this feedback forum either😔
