Y-axis scale shows twice

I updated to a few weeks ago and I just noticed that the Y-axis scale values are showing up twice - 2 columns side by side on the left side. I really don't know if this problem appeared with the last update or before that. My users on this are all in a manufacturing environment. When I noticed it and asked how long they've been seeing it they were not sure.

Anyway, what is it I'm doing that is causing the these values to show twice? I have no problem with the X-axis numbers across the bottom.




Each series has it's own Y-Axis which can be turned off with Series[Index].YAxis.Visible := False;

Exactly what I needed. Thanks!
