Page not completely duplicated

I am using a template. Some of the pages duplicate correctly but some to not. Here is the link to one of the original page and what it looks like –
https://nanoindustries.com/features/pages/about-us-2/

And here is the duplicate https://nanoindustries.com/?page_id=1134&preview=true

You can see that most all of it is missing. Please help me resolve this problem, thank you for your help in advance.
