I'm having issues where the shapes are not appearing in the Visual Overview.
Following is what I did.
In the driver I added the ;xpos to the ColumnOption options.
In the visio I added two shapes for calibration with XPos and YPos values. One is the top-left with values xpos=0 and ypos=1 and the other on the bottom-right with values xpos=16 and ypos=-1
And I added a shape with XPos = [param:*,103] and YPos = 0
Compared to similar Visios I think it's correct.
I'm not sure how I can debug it.
Any help is welcome.
