Robotank v6 - can not save any schedule

[kukulin]

Hi Rob,
I have an issue with Schedules - I can not create any schedule.
I try to make schedule for the Refugium light to start at 7pm and repeat every day.  Light is connected to one of  AC outlets and repeats every day.
When I click on Save button list of schedule remain empty
This is happening for any schedule I try to create.
Refugium AC outlet exists and I can switch it on/off manually in main dashboard.
Scheduling for lights is working (at least can create and see it in list - do not have lights connected yet, it is on my ToDo list)

Is there any specific setting I overlooked ?

My controller ID is 1193334259, running version 6.1 fresh install on formatted SD. It's running on RasPi zero W.
