I added my facebook account to my TouchPad and removed the calendar sync but I still get birthday reminders. I can't see any birthdays or events in the calendar app, even on the days where I know there should be one.

How do I delete all of the birthday reminders or disable them? The only way I can delete the reminder is to wait for the alert and delete it from the details dialog that appears. I've tried to remove and re-add my facebook account but that only created double birthday events.
