Smart Lights: Cannot set time period

Can’t seem to get the “Only during a certain time” option to hold when set.

Any ideas?

Does this mean you are entering a time in Only during a certain time but when you come back to the configuration screen, it isn’t showing up? If you proceed hitting next, does it stick even if it doesn’t show up?

I am not able to recreate, but if you shoot a note over to support@ with the OS type and SmartThings app version, we can look into it.
