Drupal 8 View title not showing in template?

Question

Drupal

I've already broken my head. I'm setting up the view. I set the title, redefine the title by argument, there is a title in the preview, but not on the page. Why? What did I do wrong?

in the template I write as in the core

<h1>
            {{ title_prefix }}
            {{ title }}
            {{ title_suffix }}
</h1>

On the page

<h1>
            
</h1>

I read a bunch of forums and docks. What am I doing wrong?
Tried to do prebuilder and prerender hooks. They have a title! Where is he lost?
