hmmm,, i'm not really sure what is causing it to be honest, when logged in as admin, it is adding an <h1> tag around the contact area, the H1 tag style is orange, the workaround would be to remove the color style from the H1 tag, but that would change all H1 tags, even when not logged in.
since it shows orange when logged in, i would be inclined to leave it as is, it displays correctly for the site visitors.
