Viewport.SetBoxCenter steamnodes twilight zone

I’m using the Viewport.SetBoxCenter node from steamnodes to reorder pre-defined viewports on the sheet.
Viewport.SetBoxCenter kan only handle 1 entry at a time so i split them.

as you can see, the x value of the bottom two elements are the same (as are the top two)

But this is what i get.

I’m using a scopebox so in size view A=B and C=D.
The points of entry in x are the same, but the result differs.

There is a problem when you have adjusted your scope box…problem remains strange
