Held tricks AR program

The held tricks quest in the AR program keeps bugging, I'm on xbox 1 and once I get to the point I have to do the held flip tricks it just keeps telling me to go back to the session marker then completed will come up at the top and hold on eventually and it won't move past that, iv completely quit and came back in the game, quit the quest and came back, nothing is fixing it so now I'm stuck in the middle of the AR program and can't progress past it, it's part of the tour 2: bag of tricks step 5/7  mission.
