Light grey "Minus sign" over bar and bold bar line
Not sure what I pressed, but a light grey minus sign appeared over my bar, between two notes and the bar line turned bold black. When I copy and paste the bar to a new score so I can share it, the minus sign and bold bar line disappears, but a note is added where the minus sign used to be. I tried removing the bar and inserting a new bar, but the minus sign shows up again. Any idea how to remove the minus sign?
