When setting up competitions in FIBA Organizer (FO) you should always ensure OverTime (ExtraTime) = 1 rather than the default setting where OverTime (ExtraTime) = 0

Refer to screenshot below: 

You can access this screen via Competitions > Competition Details (select comp) > Basketball

This setting does not effect historical comps in your database that have already been completed but should be applied to all current competitions and any new competitions moving forward.
