Sidebar not appearing on Homepage

Hello,

Using WP 3.9.1, theme Twenty Thirteen. I installed Custom Sidebars to add a Sidebar to my Homepage. That Sidebar does not show up on it.
Yes, I did set select the Sidebar I edited that post — because my Homepage is a post.
Now, earlier on, I deleted a piece of code for the posts on my Homepage not to display post metadata. Is that by any chance what is preventing my Sidebar from showing up?
Also, I noticed that when I edit the post to add the sidebar, on the bottom right corner when choose the sidebar, it doesn’t say “main sidebar” to be replaced, but only “secondary widget area.” Is that a clue to what is not working?

So many thanks in advance for your help!
