Sidebar appears at bottom of page?

Hi. i am using catchmag pro theme. I noticed if i disable "Recent Posts/Content on homepage" it makes the sidebar disappear and appear right at the bottom of the page. Why is this? Customizer > Theme Options > Homepage / Frontpage > "Check to disable recent comments". My original aim was to stop a raw list of posts showing at the end of the homepage. (but to keep everything else as it is. Any help would be greatly appreciated.
