Duplicate Desktop or Unknown service books are found in the calendar or contact list options of the BlackBerry® smartphone. This issue typically occurs after a BlackBerry smartphone has been synchronized with BlackBerry® Desktop Manager or when a backup file has been restored to the BlackBerry smartphone.

This behavior is expected when performing a wired organizer data synchronization between a BlackBerry smartphone and multiple mailboxes.
