I can't make my pages full width

I just implemented the Millipede template in Wordpress and I can’t make any pages full width. Site is simplecomforts.com. The homepage is a template that is full width (even though I can’t edit it in Beaver Builder. I can only use the block editor for some reason). Look at one of the pages linked in the navigation. I drag in a row, set it to full width and the default is 1180px.
