WP-Andreas01 Adding Right Side Bar to Sub Pages

Ok… I’m using the WP-Andreas01 theme. The home page features a left sidebar and a right sidebar, but when you go to the subpages there is only a left side bar with navagation… no right side bar with archives, categories, links, etc. I want to have a right side bar throughout the site and I have been looking and looking as to how to add the right side bar on these sub pages without much luck. So I am now asking the wise wordpress community for assistance. The site I am modifying is https://www.busylifebusiness.com. Many thanks in advance.
