One of my coworkers looked at it and said
it's split because the parts of the text either side of it are in two different <p> tags. Not sure how to stop that from happening. Any time you hit enter in the confluence editor it creates a new <p> even if you hit shift+enter it adds a <br> which will cause a break.
