Calender Reminds me of Appts 405, 550 705 minutes before...

So I wake up last night and to my calender reminder going off at like 2 in the morning. I looked and it had an reminder appointment way off that it was sounding the alarm for. I looked to what the reminder was set for and it was set for 465 minutes. I have my default reminder set for 15 minutes. I looked at all my other appointments and they varied to being set from 1065 minutes to 363 minutes prior to the appointment. I had to go back and reset all my reminders. I have search for someone that has had a problem with this and no dice. WTF is going on with my BB? It's possesed

I have the same problem. Any resolution? Thanks.
