Using Divi with WP-Members

When I set up blocked, Members-Only webpages using Divi’s Editor, the page that comes up to tell people that the page is blocked and includes the Existing USers Log In form [wp-mem-login] loses formatting.

What am I missing?

The page I need help with: [log in to see the link]
