Dynamic component copies scaling differently

[luke3]

I have made a sliding door Dynamic component that I want to have options for height, width and number of panels.
The functions are working but the panels seem to scale randomly when I opt for 3 or more panels. The scale of the panels just doesn’t seem to be consistent.
Is there a way to make the panels scale consistently with the overall frame?
