Display joomla 3 content?

Question

Joomla

Guys, how to display the content of the post on the page?
I know: Let's use this entry
But, it looks like this: joxi.ru/VrwN3QyClDygAX
How can I remove the extra, under the numbers 1, 2, 3?
I have already climbed all the forums, I have already edited different files:
components/com_content/views/article/tmpl
components/com_content/content.php
I also edited in the templates, tried to find where to remove the excess, it did not help.
Tell me how can I remove what I highlighted?

Answer 1

Through the admin panel:
Option 1.
Menu manager - Edit menu item - "Material parameters" tab.
Option 2.
Material manager - Edit material - Display tab.
And in 1 and 2 cases, switch to the "hide."
