Fan Availability Schedule

I'm not seeing the fan availability schedule being respected by the OS to idf translator. The translator always assigns the air loop availability schedule to fan availability schedule. Anyone else experience this or am I missing something???

I skinned the loop down to just two fans, a setpoint manager, and an outdoor air system to try to figure it out.

EDIT: This is related by the solution isn't applicable. If I want to disable one of the fans at certain times of the year shouldn't I be able to schedule it off using the fan availability schedule? Does that functionality not exist???
