I need help with superstar

So i was planning to make a cb player in the superstar gamemode, all went to plan until i got to the route tree(?) running minigame, where you are supposed to reach a number of zones within a set amount of time. The first four where do qb doesn't do anything goes to plan, but the next four are a whole different story, as the qb just doesn't throw the ball, no matter what buttons i press. Does anyone know how to fix this?
