Different start point in an array of rectangles!

Hi All,
I have an array of rectangular curves created in Grasshopper with a certain start point on two of them and different on the rest!! I know the Seam component is supposed to change the start point but why it happens unevenly?
Do you think if it’s a bug in the software or I have done something wrong in the process? (Snapshot attached)


Thanks

It seems your rectangles are not the result of array start from the same rectangle, but the section profiles from Brep / Plane.
So, the starting point positions vary depending on your brep. IMO, obviously it’s not a bug.
