Same issue here with a fresh install of 3.0.7. There is no option for “No Sidebar” in the Layout Box, it’s just Default Setting (Set in Enfold options) or Sidebar.
Saving one of the demo pages (which appears nice without sidebars) results in a page with sidebar and no option to remove the sidebar after saving a first time.

Edit: This other topic solved the problem, had to add the PHP code to the top of the functions.php. Seems to have something to do with the translations…
