Issues with Honeybee Set EP Air Flow command and openingAreaFractionalSched_ input

I am having issues with the component Set EP Air Flow, particularly when connecting a schedule for window opening.
It appears that, given there is one thermal zone and multiple windows, multiple nat. vent. schedules are created. From the err file:
Last severe error=Duplicate name found. name: "WINDOW_SCHEDULE". Overwriting existing object. (825.6 KB)

has anyone experience similar issues??

can anyone help please?

@andrea.botti Just use an item selector to select the schedule after custom schedule is generated.

I am attaching the revised gh file. (824.1 KB)
