I coded soprano staff to bar 20 ---- compile in v2.19.19 and no notes displayed.
Then I continue to code piano-right staff to bar 6 ---- compile in v2.19.19 and I can see notes appear on soprano staff but only up to bar 7 's first g'2. Partial bar 7 to bar 20 disapear. Piano-right display bar 1-6 as expected. However, bar 7 -20 also displayed with staff lines. Piano-left staff display bar 1 as expected because only bar 1 is coded.
Then I switch to compile v2.18 all 20 bar of soprano staff appears, however piano-right staff display all 6 bars that is coded. Bar 7 - 20 display staff lines (no notes are expected - not coded yet). piano-left display as expected. Strange .....
Strange!
