Artists/songs vanished from my stats

Yesterday I had like 3000 minutes on the band Beach House. When I went to check out today, I noticed that the artist page was completely vanished, leaving a duplicate one in which I have only 400 minutes (https://www.stats.fm/artist/28428484).

Also, I had 1600 minutes on the song “Sirens,” by Imagine Dragons, but it disappeared too, and every time I try to stream it, the streams go to the song “Sharks,” by the same artist.

Are those streams lost?
