Sidebar, Id and Title


Hello, I come from a page that I used previously (that I already stopped using it to move to this one) and a problem arose that, in my opinion, is handled differently in this one.
On the previous page

id: sanciones
title: Sanciones
sidebar_label: Sanciones

Now I decide to go to this web page and apparently when doing what is very important to detect the sidebar, the title and especially the file, it does not work, it is like it does not detect it and appears as normal text

I don’t know why or how it is used here, could someone help me?
