Switches not responding to programming

I have a new SmartThings hub and right now just a Leviton appliance module to control an instant hot water heater and a switch to control some landscape lighting. I have programmed the appliance module to come on at 7 AM and off at 8:30 PM. I have programmed the landscape lighting to come on at 30 minutes after sunset and off at 11;05 PM. So, four routines–one for each action. Neither of the devices responds to the routines as programmed. I can turn the switch on and off manually. The appliance module resists even manual programming–it says it turns on and off manually, but a few minutes later it goes back to its previous setting.

Please let me know what I’ve done wrong.
