Multiple alerts for the same calendar events...please help!

[peridoc]

I have a Sprint Touch Pro2 with the 6.5 upgrade. Prior to this (with 6.1) and now also with 6.5 installed I seem to get two reminders for most events on my calendar. For example, if I have one event set up at 5:00pm on a particular day with a reminder 15 minutes ahead of time, I end up getting two reminders about it at 4:45pm. The popup shows the reminders as 1 of 2 (1/2) and 2 of 2 (2/2) and they are for the same event. When I go to my Outlook Calendar or Calendar on the device itself there is only one event listed at that time.

I can not figure out why I am receiving multiple alerts for events when there appears to be no duplication. Anyone have any ideas on what is going on or how to correct it? Any help is appreciated.
