Little Laura on "[Theme: Misty Lake] Full-Width Page selection under Template won't stick"

For each of my pages under page attributes I have chosen Full-Width Page... and this worked neatly for all but one page, the My Story page. For some reason, it's not working here. How can I remove the side bar and have the text go full page?

Thanks for direction!
