Fret number in Fretboard Diagrams bug

Hello, I find that the fret number position changes randomly to either the left or right side. I usually cut and paste fretboard diagrams so maybe that's why. When I set fret numbers to appear on the right, when I copy and paste a fretboard diagram the fret number position appears on the left. I have to go to Style and click on the left and right button and OK to get it to go to the side I set it on.
