This can happen if the playlists have moved due to the variant playlist now being redirected to another target. This currently only works as long as the referenced playlists don't change in relation to the variant playlist, and the new location is purely due to a new path triggered by a new redirection target of the variant playlist, or a new redirection target of the playlist itself. https://bugzilla.gnome.org/show_bug.cgi?id=731164
