I think there is a bug in the display of the article title.
Show Page Heading is hidden and owever it displays the text found in the Page Heading
https://demo.dietapino.com/index.php/carnes-varias/carne-varias/aves-y-carne-de-conejo/aves-y-conejo#sort=name&sortdir=asc
The title on the left should not be displayed. Only the title located in the center of the article should remain.
The bug, if it is a bug, is generic to all items.
The third text should not be displayed, Is displayed when:
Show Page Heading ---> Show
Page Heading : ---> title
The third text is hidden by simply putting
1.- Show Page Heading ---> Hide
2.- Page Heading ---> title
