OK, this tells us that the library is not converted to the new system.
Or if it was converted, it failed to convert the existing items.
Check the properties of your library.
Look for a menu item named ‘Convert’. If there is none, Edit your library, go to the ‘Advanced’ tab and verify that both ‘Scanner’ and ‘Agent’ are set to ‘Plex Music’.
If they are already set to ‘Plex Music’, perform the Plex Dance “light” (omitting step 4) with all albums of that particular Album Artist.
