I love the Astrid app. Howver, when I create a task and set my reminder to "when task is due", my reminder often goes off long before the due date. For example, I set a task with a deadline of February 1 at noon and a reminder for "when task is due." I am already getting reminders. (No other reminder boxes are checked.) What am I doing wrong and how can I prevent these early reminders from happening?
