Can't see more than 25 pages for access levels

I can't see more than 25 pages and it isn't even showing the most recently changed pages for access levels. The notice says "showing the 50 most recent", but it's not showing more than 25 pages.

I'm just trying to use negative rules to block a page from visitors, but I can't see the page in the page list.

I would use the url groups instead, but that isn't working either.
