I am having issues with links in text box units for Coursepress Pro

When I try to add a link to an image or line of text within the units text box, the link doesn't work. Only links to other pages of the site aren't working. Outside links to other websites work fine.

I have tried to use the full URL and just the page title. After I save it, it automatically adds two dots at the beginning of the URL I just entered. When I preview and click the link, it just adds the URL on top of the existing page.
