Looking at your story, it would be best if I fixed this one. Once you get the chapter open, you'll end up with a wordwall.
The NORMAL procedure in fixing this, provided the proper breaks were inserted by the word processing program after converting to html, would be to open the chapter, click edit, and that would fix the issue. However, having looked in the database at the data, those line breaks (i.e. ctrl+enter, or enter) created by the wordprocessor originally are NOT there.
The alternative (if you don't want to wait on me, which would be wise, I won't get to it for awhile) would be to edit each chapter, by copy/pasting from your documents for this. Will it bump it up the list? Yes. In this for instance, though it's not a big deal. The important thing would be fixing the chapter.
If you're using IE, that will cause the edit block to not appear, unless you follow the instructions listed here. If that's not it, then you need to logout, then BACK in, using the login boxes located at the upper right corner of your browser screen.
