Logically, a BREAK (like, say, a COMMAND) cannot have a Ramp.
BREAK items in my Playlists here always show a Ramp of 0.0, which I consider a bug. I don’t feel that ‘Always show ramp’ should apply to non-audio items in a Playlist; neither do I think it should depend on your ‘Show break duration’ setting.
