Blog template not displaying

Hi,
I create a page where I add the last entries from a ready-made template, in the editor I see these last entries (attachment below):

And when I go to https://olamumtales.com/blog/ they do not display.

And I don’t know what I’m doing wrong. Because when I already enter, for example, the categories https://olamumtales.com/category/education-and-development/ the entries are displayed.

Asking for help.
Greetings, Konrad.
