UPDATE: I was able to fix this by DEselecting “Allow Document Pages to Shuffle” and “Allow Spreads to Shuffle.” Or perhaps I only need to do one of those, but I was trying everything in the book and happen to uncheck those. Once I deselected those, I was able to move the spreads back to the way they needed to be. Of course, I had to do each of them individually, which would be tedious if you had a very large document already created. Definitely something that I will have to remember to do at the beginning of creating a document. (Luckily, this particular one is only six pages.) I’m wondering if there is a quicker way if this issue returned.
In a legal document, it's rare for every paragraph in the document to be numbered. Usually, you change between numbered paragraphs and non-numbered (plain) paragraphs of text. When Word sees you switching between these types of formats, it usually tries to help by restarting your numbered list back at "1" (or the first value of your list, such as "A"). There are a few different ways to make the number follow the last number of your paragraphs. In Word, this is called Continue from Previous List.

You will occasionally want to place an unnumbered paragraph in the middle of a sequence, but the moment you hit Enter, another paragraph number pops up. To fix this, toggle paragraph numbering off by pressing the paragraph numbering button you used for the previous paragraph. (If you use the button’s drop-down, choose None as the numbering scheme.) Unfortunately, the paragraph settings won’t revert to Normal here; it’ll usually have the paragraph indented 0.25. Use the keyboard shortcut CTRL+Q to strip paragraph settings out, then revise the formatting as you wish. numbering in coreldraw
