Compilations randomly appear and disappear from the “Albums in my Library” section in the Overview tab on artists pages. They also randomly switch between the “Main Albums” and “Compilations” sections in the Discography tab.
I am talking about compilations of a single artist who is the primary artist, not multi-artist compilations where the primary artist is “various artist” . For Bob Dylan, I have over 100 albums in my library. 25 of these are tagged as compilations where Bob Dylan is the primary artist, e.g. Bob Dylan’s Greatest Hits, Biograph, Masterpieces, and all of the Bootleg series albums. These should all show up under “Albums in My Library”. Sometimes they do, when I first go to the artist page, but then they will disappear from the list after a minute or so. If I go to Discography, sometimes they will show up in “Main Albums”, but sometimes they move down under “Compilations” where they appear together with all the various artists/soundtracks.
This or something like it appears to be happening to me too (was stoked to find your post to confirm I’m not crazy). I’ve got my core (updated) on a Ubuntu Linux server, and a much smaller library. I can search for the “missing” album, but it refuses to show up in Albums in my Library. I don’t have enough time to mess with it right now, but I’ll report back if I find a solution.
Unfortunately this is not fixed - see this duplicate thread;
As mentioned in that thread, there should be separate headings for “compilations” (i.e. all tracks by that artist) and “with various artists”. These headings can be renamed as Roon sees fit, but there should be this distinction on the artist page.
