Can't add new section under existing section

Hello!
I’m having trouble adding a new section under an existing section for my website mock-up. Currently, section 1 has two divs that splits it into a left side and a right side. My idea is to have 3-4 sections stacked on top of each other; one for my projects, the next for information about myself, the third for a “contact me” page, etc. Once people are done scrolling through the content in section 1, then section 2 will scroll into view, and likewise section 3 will follow.

The problem is, I can’t add a second section (labeled "section 2 ") directly under the first. When I drag it into place, it shows up in the navigator but no matter what settings I do, I can’t get it to sit under the first section.
