Why does an album show up in my Qobuz library

Why does an album show up in my Qobuz library when it is not one of my favorite albums in Qobuz? It is a recording of a Bruckner symphony by Berlin Philharmoniker. I was able to remove it from my albums easily enough, but I wonder why it was there in the first place since I never even played it before or made it a favorite.

Roon has an FAQ for that question, maybe it helps?

Thanks for the article linked. It was helpful to learn what is written, but in this case the album showed up in my Qobuz library on Roon but did not show up on my album favorites page in the Qobuz player for Windows. I double checked and it only showed up in Roon. I removed the album in Roon and it hasn’t showed up again. Weird. If someone had hacked into my Qobuz account and favorited the album it should have shown up both in Qobuz player and in Roon.
