Just purchased the Maltby Golf Club Gauge, still learning how to use it and I encountered this problem.

I am measuring an older set of Mizuno mp 14, on some of the irons, when I line up the scoring line with the straight edge, and then slide 2 pieces of paper underneath the club, they do not measure equal distance from the center line. However, when I get them to measure equal distance after adjusting the lie, I cannot get the straight edge to line up perfectly with the scoring lines.

Am I doing something wrong?
