Fan Schedules not restoring original fan mode

I have a Qolsys IQPanel 2+ and ADC-T3000 thermostat. I normally keep my fan configured for Circulate mode. I’ve recently begun to use Fan Schedules, as there are certain times of day when I’d like to run the fan constantly.

The Fan Schedules work normally in that the fan changes from Circulate to On according to the configured schedule. However, I’ve noticed that when a configured ends that the fan gets set back to Auto - not Circulate, which it started from.

Is this a known issue? It seems to me that when a schedule ends that the fan should go directly back to the mode that was set prior to start of the schedule.

According to Alarm.com, when a specified number of hours is selected (i.e., 1, 2, 3, 24 hours), the fan stays on for the allotted time frame and then reverts to Auto mode.

This applies to both manual fan control (from the TSTAT card in ADC) and to Fan Schedules as well.
