No Blog Page – Not Correct Page

Sorry to bother, but I do not seem to have a correct Blog Page.

This is what the PP demo shows it should look like:
https://dp1.wlthemes.com/blog/

This is what shows up on my site:
https://www.onlinesellerslunchclub.com/blog/

I added a Categories List to the side bar to be sure the blog posts were out there – and the sample posts are, along with one that I modifed.

Don’t know what I’ve missed. ??

What I checked:

1. Customizing – Static Front Page. Has “Blog” selected for Posts Page.
2. Theme Settings / General Setup / Page and Button Links. Set to Blog.
3. Menu set to Blog
4. Updated the Blog page to be sure it was active.
5. I tried viewing: logged in and logged out.

I have not edited the Blog Page.
It does not have a parent.
It says:

You are currently editing the page that shows your latest posts.

Please tell me what I’ve missed. Thank you!
