I went to the example you provided and could not reproduce my error (unable to clear page from background image even after deleting its path). I went back to my site and that anomoly still exists. This is a dialog box that I do not have any control over so I cannot tell why the path will not remove upon deleting it. What is the date of the version you used in your example?

 

 

I successfully added additional fonts to the editor. As I select a font, the font name appears in the dropdown box, except for a few. Although the fonts work, their names do not display in the box like the others. Instead the word "Default" appears. I am wondering why those few fonts do not accurately display their names while the others I've added do.
