Page looks different when duplicated to live URL

I created an updated version of an existing page: http://etrainu.com/all-online-courses/white-card-update/

But when I copied the values from the code block at the bottom of the new page to the existing page, the layout changes: http://etrainu.com/white-card/

Are you able to advise why the padding values would change?

Thanks for your help.
