You do not have a link list with a handle set to for-the-van-aus-new-zealand-store, or you do and it's empty. Go ahead and create a link list called For The Van "Aus/New Zealand Store" on your Navigation page and populate that link list with links that point to collections, to see collections listed here. Make sure the link list also has a handle set to for-the-van-aus-new-zealand-store.
