Calandar erasing events after about 30seconds

First time using calandar after update and i'm having some problems. Mainly i will enter a new event and it saves and shows up, but if i look at the calandar it just disappears in a few seconds.

Do you have calander sync set up? This happened on my Eris. I had to fiddle with the settings. My corp and google calendar syncs were erasing events I added to the calendar from the phone.
