Since there is currently no way to edit HTML under the new code, it's impossible to return an editable area to an unused state after using it.  Simply typing none in edit window in the new admin edit area actually leaves HTML code of "<p>none</p>" so that the word none appears on the home page.

Only by going to the old admin area can we edit HTML and get rid of that code so that the home page editable areas remain blank when not being used.
