Full width page has sidebar

I selected Full Width for my Listings page but the side bar still shows up floating to the left underneath the listings content. Also, only Default is showing up as template choice in the Single listings page. Even though I have several templates installed. I just don’t want a sidebar showing up. And if it does show up, I prefer it to be on the right instead of underneath all the content.
