Pages not showing in on the back end of site.

Hi,

When I create new pages, they show fine on the front end but they are not showing on the back end. Specifically, page one of the "page" directory shows but when I click on page two none are present. It just shows the "about" page listing again, no other pages and the numbered pages in the directory on the top right decreases from 2 to 1. However, the All and published buttons on the top left always show the correct number of pages.

I deactivated all plugins and it did nothing. But when I switched to twenty fifteen, and twenty thirteen, the issue was resolved. All the pages are present and I can toggle between the 1st and 2nd pages in the directory.

Thanks for any advice,

Brandon
