Folder RSS Feed - XML Export

I’m looking to import the Folder RSS Feed into a site where the articles will populate a news sections. I know all the information I need should be coming through the XML for the Folder RSS Feed, but when I check the XML on a browser, it only contains 1 or 2 stories.

Am I expecting something that isn’t here, that is, a new feed that contains all the filtered stories I want in a single, updating feed another reader or website can use?
