Entire page content does not display in Word output

When I have created a page that has a lot of text content, the export to word/pdf does not display everything that is in that text box.  Is there a setting that needs to be adjusted for that to display?  User can scroll down in the html course to see it, but just not visible when exported.

I have attached examples of the page design in the 'course' and 'preview' views, and the export to word.
