HC3L Sunrise and sunset timers not working

[AHornak 0]

I'm new to Fibaro, having migrated from Vera. I have a new HC3L and I want it to turn some lights on after sunset, but I can't get the sunrise and sunset timer blocks to work.
Other time blocks like "Exact time" and "time interval" both work fine - I set up the time block to turn a  light on and off and this works -the light turns on and off as expected.
But when I set up a timer  using the "sunrise and sunset" block, such as "1 hour after sunset" I can save it OK, but the light never't turns on

I've tried this with hours and with minutes, and simply "at sunset", but the light never activates.

Clicking the "Run" button works. I've checked the clock in Date and Time, and it's correct.
Any suggestions please ? Is there a lua equivalent that might work ?
