Bar/measure moves to next line when I try to alter one note.
I am using Musescore 2.3.1 on an iMac. When I try to change an eighth note D (PERFIDIA INTRO 1 ATTACHED) to a low A, the entire bar/measure containing the eight note D expands and moves down to the next system (PERFIDIA INTRO 2 ATTACHED). Can anyone help me resolve this problem? Grateful for any advice.
