Responsive Widget not sitting below properly. Formatting issue

Help!! Normally my widgets roll down below the main content when I am on a mobile device, but for some reason they have changed. They are still below the content but they are not taking up the whole area. My left widgets are shrunk and on the left and my right widgets are shrunk and on the right with a big space in between. I restored my template to default thinking I may have done something, but it didn’t correct the problem. Any ideas?
