I have been trying HA 3.0 for a few days and really love it! Works like a charm, everything but the scheduler that is

If I create a schedule with only 2 activities that are sun controlled it doesn't show in "Upcoming events" and nothing triggers. However if I follow the example from the documentation with static triggers as first and last it shows in the event list.
Am I missing something or is it not supported to only use sun controlled triggers? In my case I would like to turn my outside lamps on upon sunset and turn them off again upon sunrise.
Edit: After some more fiddeling with this it seems to work if I change the order so the first activation is "turn off at sunrise" and the last is "turn on at sunset". A bit strange perhaps but I guess there are some heavy logic to handle the canceling out problems in combination with static activations
