Wondering if I selected the wrong blog post type so images are not displaying in Category pages

I had a problem about six months ago with some of my blogs where their images were not displaying on Category pages because I had created blogs of the type Video instead of a regular blog. I have just come across three more blogs whose images are not displaying in their category view pages. I am wondering if this might be the same problem again. The last time you changed the blog type for me in the database.

Both of the blogs on this page are not displaying image or introtext:

a couple of blogs on this page appears to have the same problem:

https://www.drcarney.com/blog/health-testimonial

The title of the blogs in question are:

"Sheila Lewis Chose Diet Instead of Bypass"

and

"Ruth Heidrich Beats Breast Cancer"

I am wondering if this is caused by the same problem that we had discovered six months ago for some other blog posts?

If so can you change their blog type or tell me how to change their blog type?

Thank you very much,
