More detail is needed. Are you on a corporate BES server? There are some issues with the process on the BES service. If the Z10 is on a BIS and you have checked to insure old calendar appointments are either deleted or archived then it may be a new bug you have found in the new OS. Rim does not list any issues I could find.
