It shouldn’t be doing that actually because the container is a 12-grid column wide layout… judging from the menu items I see, my guess you did not create a custom footer menu? This one looks like a fall back menu (a temporary menu that WP puts in from the available pages you have). Do you plan on having a menu there?
I’m currently rebuilding the Preference theme and just made a note to make sure it doesn’t do that.
