Solar Envelope Ladybug

Hi everyone,
I was using the solar envelope component (Ladybug), but when I try to double-check with a 2h-shadow study, I can see that one of the surrounding buildings would be in the shadow for more than 2h. So now Im wondering what exactly defines the height of the control points of the polysurface, because in the description it says that it ensures that the new building wont shade the surrounding buildings.

Thanks a lot in advance for helping me!
