2nd volta line missing at top of page
Version 184.108.40.20666 Rev.8ca4d2c, Mojave 10.14.2 on macBook Air.
When I insert a break so that the 2nd time bar appears at the top of the page, the line above the 2nd time open volta disappears. It was there in all staves when that bar was at the foot of the previous page. If I select 2 bars and then insert the volta the line is there, as in the bass stave of the attached score at bar 18.
