Problems getting page full width

I have set all of my pages to full width. In addition, I have a page builder plug in by Site Origin, and I set the rows to full width. For some reason, I can only get pictures that I insert into the Page Builder rows to go full width on the home page. Despite the pages and rows being set to full width, I can’t get any of the other webpages to actually go full width. What am I missing here?
