It sounds like you need to specify the ShadowCalculation object. Note that it says, "By default, the calculations are done for every 20 days throughout a weather run period; an average solar position is chosen and the solar factors (such as sunlit areas of surfaces) remain the same for that number of days."
It looks like you either need to update the Shading Calculation Update Frequency field or change the Shading Calculation Update Frequency Method field from Periodic to Timestep.
