This is probably a rare case - but attached is a dummy score for flute and string quartet, in which the flute part starts with a cadenza with several barlines that are only in the flute part. Then everyone has a regular bar 2 together. When I look at the flute layout, the bar numbers all look correct, but any rehearsal marks are just empty boxes.
I first noticed this in a cello concerto I’m writing, and then I made this attached score to see if I could reproduce this. Thanks in advance for any ideas!
