I have a similar issue where the “Timer has reached a duration of” trigger is not working.

In the example below:

- The timer starts as expected
- The trigger “Timer is finished” is triggering the notification
- The trigger “Timer has reached a duration of 5 seconds” is not working

When I understand that trigger card correctly it should trigger when 5 seconds of the timer are remaining.

Does anybody has an idea how what is wrong here?
