Why do I have duplicate CB flights in my light list?

In rare condition you can see the same flight on your CrewBriefing flight list in PPS.
Normally this is due to one of the following reasons:

Used Create Copy

A duplicate of an existing CrewBriefing Flight has been created by using the Create Copy function is PPS

Changed STD in your schedule system

If a flight already has been created via Auto Dispatch with data from your schedule system like PDC, LEON, FL3XX, Skylegs etc and the STD is changed in this schedule system and synced to us, our Auto Dispatch will treat this flight as a new flight and then create the same flight as duplicate flight with identical information.
