Dave,

Just as a test I reset all 7 tracks in the song I am working on, saved then saved again using Save As and a new suffix. There are no other copies.

Closed BIAB, then reopened and opened files from recently used list, all tracks reset to "Force Track to Simple Arrangement"

Closed BIAB, then reopened each file from Explorer, all tracks reset to "Force Track to Simple Arrangement"

Strange behaviour, but now I know the cause of the RT silence, a minor inconvenience, not a big deal.

Would be nice to have it fixed though.

Thanks for your help and explanation re the lack of simple bars in these RTs.
