When editing a page, data is missing from the page

When I go to edit the "Important Links" section it completely disappears when I press edit (See screenshots)

Did you copy and paste from an html page?  You could have extra HTML on the page that is causing issues when it is in edit more.  You should use clear formatting option to see if it fixes the issue.  Just highlight the page or section.
