evan, in a multi-staff instrument your musical line can move from the lower staff to the upper staff and back again. In these cross-staff situations there should not be any rests shown in the staff the line just left. Your above example looks like such a case.
I have now the same problem, but as you can see the last rest in bar 165 is not showing as Ends Voice… still there are missing rests for 12 bars (and the next shown rest does not show Starts voice)
Again and again these minor glitches disturb the flow of my work…
When I try to input via caret, it works… but then I don’t want the left hand playing… and when deleting the inputted notes, again no rests… frustrating
Interesting, for some reason the bar rests in bars 7-8 were in a different voice than the preceding/end bars (showing voice colours indicated this) and the bar rest in bar 6 had the Ends voice property set.
Simplest way to solve: select the bar rests in bars 6-9, and press Delete.
In case it’s helpful in other situations, the other thing I checked was whether any of those bars had music crossed to the other staff, which you can reset from the Edit > Notations > Cross Staff > Reset to Original Staff.
