If anyone has beat this game can you please pm I have a question. Thanx

Sorry to reply to my own post but heres the question I have:

I am 95% done, Under the skill tasks list there is one that says. "Kurt Busch Greg Biffle share draft each other", I have done this several times in season mode but it is not eliminating the task from the list. Do i have to do it in another mode or is there something else I have to do along with it that I am not aware of?
