Hi Kendra-
Sorry about all the trouble! You have found a bug, and we’re working to fix it, but there are some workarounds you can try. Here’s a copy of my original response to your question:
Thanks for reaching out! I experienced the same issue as you so I’ve filed a bug report for our developers to fix this.

The second work-around is a little more difficult to do at first, but will let you edit your call-to-action visually. Open the widget editor, right-click on the editor window, and click Inspect or Inspect element. Then, search for the element called <body id=”tinymce” . Double-click on the class section, and remove the class page-template-default:
