I downloaded your posted .MGU file and opened it in my copy of BB.

Had to hit GenPlay in order to populate the autoaccompaniment tracks after loading the songfile. That's normal, or I won't see those tracks, only Melody.

Was able to do exactly what you want the first try when going into LeadSheet view and simply clicking ctrl-Bass to see both tracks.

And that is because my Notation Options are already set up to do that, reread what I told you to do earlier.

Chart looks fine, Print Preview looks fine, Prints fine, with just one Treble staff with Melody on it and just one Bass staff with the Bass part on it.

Of course, if you've already done that and no joy on your end, try the Options -> Return to Factory Settings inside BB because sometimes the program's volatile files become corrupted and that is what the Return to Fatory is there for.
