Had hoped for a bit more feedback on my last post - 1 reply... would've expected some PG guys to step in...
Needless to say I'm still dealing with the 2 issues..

Here's the 'new' problem - I save a song - and UNcheck the piano patch so it doesn't get saved... sounds fine in BIAB - so I render it, and play the WAV file, and the piano is in there!! So either I'm doing something wrong, or this is a bug....
