Can't set light schedule for spotlight cams at night

I've been trying for over 1 hour to set a light schedule for my front yard spotlight cam lights to turn on from 8 pm to 6:30 am every night. But no matter what I do, the blue button at the bottom of my app screen won't let me "save the schedule". I've been on the phone with support for over 1 hour as well and the lady seems clueless. I'm not an idiot. I have been able to set light schedules for ring lightbulbs with no problem, I understand how to set up a schedule. I can set a schedule for my front lights to be OFF all day, that's no problem. But if I try to set up schedule for my front lights to be ON all night, it won't work. Please help.
