Sorry, my fault. That did the trick. I enabled "all events" since in first versions this was only setting which enabled alarms from alarmed. But after update I just forgot to play around with this setting.

One strange thing happened today: I set up an event in calendar for sunday morning 9:00 with alarm at 8:30. And nextalarm shows remaining time as 1d 17:44. The '1d' is too much. The alarm will occur tomorrow not on monday. Also other alarms don't show correctly and often have one day too much.
Seems like you show Xd every time the alarm is not today. Maybe you can try something like (<TIME div 24>d <TIME mod 24>), i.e. the same algorithm for both parts of the presentation. (I hope it's understandable)
