Weird page setup

The usual display for the page (it being centered) has been replaced with the page pushed all the way to the far right, and then when i get to the second page, the second page is pushed to the far left. How do i get it back to the regular page view?

EDIT: NVM figured it out. For anyone who may find this later in history, there are tiny icons in the bottom right that depict 1, two and two pages right next to each other. They change the view.
