Post page contains no side bar

Although I have a side bar on each page of posts, there is none on the post page itself. https://thegloriousrevival.org/posts/ I have set the default template to side bar, even though I don't use sidebars on any pages, just so I could have a side bar on the post page, but none shows up.  I would like to have the post categories there. I am also not actually using posts on the home page. The site is set up for static home page, right side bar.  See below.   AND
