Blogging: How do you add new post?

As instructed, I made new folders in GitHub Pages | Websites for you and your projects, hosted directly from your GitHub repository. Just edit, push, and your changes are live. as below

However, I only see the first file on the posting list, not the second and the third one.

Does anybody experienced same issue?
Any solution?

Thank you for your consideration.
