Wondering why Sidebar2 position does not display in widest width view

I am sure I set this up somehow but am not figuring out what is causing it. Basically if I narrow the width of the browser then sidebar2 displays like I want. But, if I make the browser wider then sidebar2 displays underneath the blog posts instead of to the right of them.

I am trying to upgrade my template to be the most current version of Charm and maybe that will fix the problem. But, otherwise, I am wondering if there is a setting in the template that I am missing.
