You will edit the navigation by going to Content > Pages > Navigation. Some things to note:

1. Any navigation heading (parent) that has a child item should not be linked to a page. For example, "Start Here" and "Style Guides" in the image above are parents that have children items underneath them. They cannot link to another page because they are triggers to expand that part of the navigation.

2. The bottom links are not edited in the navigation, rather they are edited with a link list. You can edit these links by going to Content > Link Lists > Navigation Links

3. The "Times and Locations" option shows a campus selector and displays information from the campuses listed under People > Churches
