It relates to the Layout settings only, you assigned these pages to 'ja_seven - Home 2' template style. However, this template style loads home-2 layout which doesn't include 'component' block - the main content block of a page - so nothing showed there.
You should assign 'ja_seven - Home 2' to specific pages like homepage of your site only. And set 'ja_seven - Default' as default template.
I just did it for you and it's displaying correctly now.
