Ranked adventure - Sometimes get 7 races in dirt events

Anyone else notice that sometime instead of the normal 5 events in ranked free for all we instead get 7 events. After 5 events the 6th event is labelled 4th event.

I’ve had this several times today. Pretty annoying if you’re say in 2nd place after 5 events then make a complete hash of things in race 6 which is free roam rush and lose your placing.
