Exceptions to daily recurring events occurring in GMT shadow are duplicated

Exceptions to daily recurring events occurring in the Greenwich Mean Time (GMT) shadow and created on the device show up incorrectly in the CommuniGate Pro web client.  A duplicate appears on the exception date and the next day's instance is removed.  Using the Outlook Connector, they appear correctly. 

For time zones west of GMT (Prime Meridian or Longitude Zero), GMT shadow is defined as the hours of the day after GMT midnight - for example, after 7:00 p.m. EST.
