Suddenly the lines in my swing meter have changed/disappeared. When I am hitting a club and especially when putting the only lines visible on my swing meter are the start line on the far right and the “full swing” on the far left. All of the lines in between ( used to judge 1/4,1/2,3/4 swings) are gone so I don’t know how hard I am swinging the club. Anyone know why or how to fix it?
