Shading Designer Component Error

Hi All, 

I posted last week but got no replies so I'm re-posting this! If you know how to solve this issue, please help me out! 

I am trying to use SHDDesigner component to figure out depths for vertical shading devices. Thanks to hydra share, I was able to use the shading designer example file. (linked here:http://hydrashare.github.io/hydra/viewer?owner=mostaphaRoudsari&...)

I set the horOrVertical input as 'vertical'. But now I get this crazy shading surfaces floating middle of nowhere.. I have attached the gh file and screenshot below. 

It works just fine with horizontal shading device option. It would be great if I could get some help on this! Thank you
