Blog post disappear

Although my blog posts still exist on my dashboard, the post disappears (in excerpt form and complete post) from blog pages on website. Photo & title appear …. but no content.

Latest blog post on home page appear with featured photo & excerpt as well.

This seemed to have happened when I switched to permalink with post name. I know if go back to defaul permanlink all will be ok. But that’s not what I want. Any suggestions. I’m a newbie…so be gentle. Thx https://www.market-inc.com
