When I look at the Reminders Windows, I notice that the reminders aren’t listed chronologically.

My 6 reminders are now sorted like this:

1. 15 hours overdue
2. 4 days overdue
3. 3 days overdue
4. 5 weeks overdue
5. 7 weeks overdue
6. 4 weeks overdue

Why is it sorted like this and how can I change the sort order?
