Hi Henrik, you've actually stumbled across a bug in the sequence log which I fixed only a few hours ago.
When one sequence triggers another (as your sunrise sequence does) the original sequence is logged multiple times. As it works through your sequence, this is what was happening in the logging:
If you drill down into the steps run in both the sunrise sequences by clicking the magnifying glass, you'll find no steps are logged even though steps ran.
This is now resolved, so future instances should only log once and will also capture the steps which ran.
I can confirm that although it appeared twice in the log, it wasn't actually being run multiple times.
