Title only - No content

I created an article in a brand new J4 installation and I can see the article in its category. When I try to create a menu item to that article, I can see only the title, but not the body of the article. Also why is the article body named "Description"?
Thank you 

hello you need to check your item template
got to type > yout type > check template used
go to your template and drag and drop wanted field in desired position

The item template contains the field "description" (still puzzled by the name convention)
I can't see the article content only when I create a menu item directly to the article. If I go to the category view (blog view), I can see the article. Is there any instructional video on this?

can you send screenshot and link to understand more ?

   

This is a test article linked to the Flexi link in the menu. The article has a long Lorem ipsum type of text. Nothing is visible.
I want to ask again, what is the "Description" filed as only that one has an editor. Is that the content?

 

hello
in your template (flexicontent) assigned to your item type did you drag and drop desription field ?
