Hi Sandy,
Thanks for your patience. I've received confirmation from our team that this text is indeed intended to be in the document and there's nothing to worry about. Keep in mind that the text on that page is intended to be placeholder text, as it's a general guide on how to read the document. Normally, a standard lorem ipsum(
http://en.wikipedia.org/wiki/Lorem_ipsum) is used in these cases, however our team thought it would be fun to rewrite it as "Zombie Ipsum" with a few references to the popular TV show, The Walking Dead.
I hope this helps clear up any confusion.
Regards,
Jeff
