Microsoft Word is adding extra space between words as I type

Word is adding space between words as I type. Here is the layout of my document:

It simply consists of two pages with the first page being vertically aligned at the center. In order to allow for a normal top alignment for the following pages, a section break was added. Look at this GIF for a visual of what is going on:

Notice how the spacing between the words change as I type. I tried removing the section break, but it did not work. How can I fix this issue?
