I have started playing with building a website using Rock as the CMS but keep running into layout issues. Instead of the left sidebars sitting along side of the main section it often shows up above the main section. The right side bar shows up below. And on several pages I have had section B, C, and D stack themselves rather then sitting side by side. 

I tried zooming in and out thinking it had to do with the site being responsive but that didn't solve anything. I also changed themes and layouts several times hoping to narrow down the cause but none of that seems to help. 

This issue only happens when there is content in the sections. When sections are empty they appear as shown in the manual. 

Has anyone else had this problem. Any suggestions?
