Slash voice position

why is the note changing which line it sits on? Plus I’m not able to move it after it becomes a slash voice note.

I believe you’ve changed it into a downstem slash voice. Try turning it into an upstem slash voice to avoid the bar rest. There’s also the slash position property in the lower zone, if you want to keep the bar rest.

Legend, thankyou
