Changing the layout of store pages

Hello,
I’ve recently installed your plugin and am tryin to change the the page layout but am having a hard time doing so. I can’t seem to turn them into a static page and get rid of the sidebar and comment box. You can view them here https://www.resultsrealty1.com/product/riches-from-rentals-book/ and https://www.resultsrealty1.com/product/riches-from-rentals-on-cd/. Any help on how to get these switched would be appreciated. Thank you.
