Roon can't add track if album is already added

I like to add albums or/and tracks to see them as favorites in my Qobuz app. I noticed that if I add a track to the library the track will be favorite in Qobuz but if I add the album before adding the track, I cannot add the track alone. The album will be favorite to Qobuz, but cannot add any track in Roon to be favorite in Qobuz. Is this correct?
