The two pages are using different CSS files. The one that doesn't appear to be showing content actually has the content, it is just printed in white because it uses:
http://sds-2018.your-adi.com/_Styles/SDS-Global.css
and on line 27 that file specifies that all <h1> content should be white.
The page that works doesn't have that css file, so the content appears differently.
