Lady Bug sunlight hours result not accurate

Hey Guys, 

I seem to be having a peculiar problem with Lady bug. I'm trying to get sunlight hours for a list of geometries but the result seems to be incorrect. It would seem that I would see more solar hours on the south side but every time I run the simulation the result shows the south side to have the least number of sun light hours. I have attached the .gh file below along with the epw file. You might have to load the epw twice. Would really appreciate the help. 

Thank you!
