Me and my sister have both N9s and we have a problem with events disappearing from the stock calendar application.

Every event that is not a repeating events is not visible in the calendar if it is about a month or more in the future. It seems to me the calendar is not loading them at all. If I go to manage calendars and edit one's settings and press cancel, the events get refreshed and it loads all future events and they become visible. After a reboot they disappear again.

Has anyone else had this and have they found a solutoon?
