As I was mucking around in Moodle I discovered a shortcut for adding and removing course sections in a moodle course. It used to be that you had to go to Edit settings and change the number of course topics or weeks. That is no longer the case.
There is now a shortcut button within the course page itself (below).
To see the buttons, turn editing on and scroll down to the last section in your course. You should see these buttons located on the bottom right corner of the last section. You can click the "+" or "-" to either add or remove a section from your course.
