Show child pages by menu order using Superfish Dropdown menu?

Question

I'm using the superfish dropdown menu to create a drop down menu.

It's created the menu fine showing all the parent pages with the child pages in drop down's below.

The only problem I have is that the parent pages are by menu_order which is what I want but the child pages are not by menu_order. How can I make it show the child pages by menu_order so it mirrors the backend?
