Created Competition Help

Hi I created a new Australian League called the Australian Premier Division. I then created the Australian Championship then the Australian League 1. However though when I go to test nation rules, it comes up with "teams should not be promoted from the Australian Premier League as their is no division above it". So what I'd like to know is how do you get the League 1 top teams to be promoted to to the Championship and then the top Championship teams to be promoted to the Premier League? any help is wanted cheers :D
