When I try to implement both natural ventilation and night flushing in my model, I get this error "1. The simulation has not run correctly because of this severe error: * Severe * <root>[ZoneVentilation:DesignFlowRate][C1NatVent0] - Missing required property 'schedule_name'."

To make the model more clear, I defined two Honeybee_Set EP Air Flow components one with natural ventilation type as 1 for window natural ventilation and the other as 3 for fan-driven ventilation. In addition, I defined respective night flushing schedule via Gene Pool with corresponding openingareafractional schedule to make night flushing works only at night-time. Although the model works fine when only Natural ventilation is defined, I get a severe error when I try to implement both ventilation types. Do you have any suggestions about how I can solve this problem? Thank you for your answers.
