Worlds Mission Bug Or just the beginning ?

was trying to finish up the worlds missions, I completed all but 1 that being a real challenger, counting all the missions i completed I've done 1:Welcome to worlds 2:Skill Quick to win 3:Fight for glory: Complete 2 missions 2/2 4:Teamwork 5:(Master pass):Resilience 6:(master pass):Courage 7:A Real Challenger: Complete 4 missions 3/4 (Is this one bugged?)<<<<< ^^^^ There are no more missions to complete A real challenger

I just wanted to check if this was indeed a bug or not or if we were even intended to finish this mission or not because i'm sure that Missions 2,4,5,6 should have completed Mission 7

I'm assuming there will be more missions weekly? maybe?
