Shared sub-calendars not displaying appointments

Creating appointments in the shared calendars show up in the main calendar instead of the shared calendar.
Selecting Show in Main Calendar makes no difference, the appointment never displays in its' proper calendar.
Appointments created in shared sub-calendars display only in the parent main calendar.
Shared sub-calendars do not display appointments correctly.

Update to GroupWise 2012 SP2 build 80211 should resolve. Otherwise, it has been reported to engineering.
