Honeybee Ep Context Surfaces

Hi everybody,
I have a problem with honeybee context component. I want to get a new lighting schedule based on natural light and I have some contexts as shelves in my room, but when I connect the context component (contains a simple box as a brep) to ‘honeybee run daylight simulation’, it goes back to the schedule that I defined earlier (It means the natural light doesn’t have any effect on the lighting schedule).
What should I do to fix it?

Thanks in advanced
