Unable to schedule GWN7000 traffic rules


According to the online manuals for the GWN7000 regarding Firewall Traffic Rules (link below), there appears to be an option to set a schedule for the traffic rule (e.g. start/end date, start/end time, weekdays, days of month, etc)

However on my GWN7000 (firmware, I don’t see any Schedule fields?
I navigate to: Firewall > Traffic Rules
And when trying to add a rule (either Input/Output/Forward), I don’t see any Schedule fields?

The PDF here shows a table and screenshot of schedule fields (near the bottom):



See if there is not a separate sett8ing by which to set a schedule and then go to the rules and add the needed schedules.
