"Post Order Number": How to re-order courses on admin page?

I have selected "Post Order Number" in settings as my course order.

In the instructions is says:
If you choose "Post Order Number" you will have option to reorder courses from within the Courses admin page.

I am on the "Courses" admin page... and I don't see any way to re-order my courses. Can someone help me understand what I should be looking for?
