I assume you mean Due Soon, not Available Soon, right?

The notification process is driven by the change in state (including starting/waking up and noticing that something has become available/due soon/overdue while the application wasn't running). You are only going to get the notification if the action was in existence when the available/due soon/overdue time arrived. If you have Due Soon set to be 3 days, if you enter an action that is less than 3 days in the future, you will not get a notification. Clear as mud?
