Unable to 'enable' Sunset

Unable to ‘enable’ Sunset.

I have a preset that I would like to come on at Sunset and I am using an “Off” preset at 11:50pm to turn my lights off. In Time/Macros, I have specified my location, used the first value row to specify the off time and enabled it. This is working as expected.

I have used the ‘Sunset’ row to have my “On” preset trigger at Sunset however, after selecting ‘enable’ and saving the schedule, the ‘enable’ toggle does not stick. Subsequently my lights are not coming on at Sunset.

The preset does work as expected when selecting it manually.

Please advise,
