Mismatch Pileup GRAPH does not respond to the graph adjuster tab to readjust it's y-axis

Draw mismatch pile up graph, activate the y-axis label.

If you change the mismatch pile up height using the graph adjuster 'by value' (eithe max or min) the image will change but the 'y-axis' label will not reflect the change. Then if you do anything to the image (click it, move it, zoom it) it will snap back to the original size.
