Page Code

I noticed this code is in most pages, but it doesn't seem to matter (on the front end) if it is there or not. <div class="entry-content"><section id="builder-section-1417714923057" class="builder-section builder-section-first builder-section-text builder-section-last builder-text-columns-3"> <div class="builder-section-content"> <div id="builder-section-1417714923057-column-1" class="builder-text-column builder-text-column-1"> I tend to keep this line, <div class="builder-text-content"> but not sure if it needs to be there once, or for each column? I am adding columnLeft and columnRight classes to the page, and to the custom css, and this code makes it confusing to read - ie where to insert my code. I have my page layout defaulted to full page, no side panel.
