If I insert a single responsive ad unit, my entire site is filled with Adsense

Hello, I have a problem with Adsense ads. I want to place ads in certain spaces on my site with the Elements positions. However, by placing a single ad, everything is filled with advertisements.

I have just created a block, however my site shows multiple ads.

How can I control where I want the advertisements to be displayed. I would like to show ads in only 4 positions.

Thank you

This is the code I have inserted:

ELEMENTS - HOOK - INSIDE CONTAINER - DISPLAY INTIRE SITE

<script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- nside Container -->
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-xxxxxxxxxxxxxx"
     data-ad-slot="xxxxxxxxxx"
     data-ad-format="auto"
     data-full-width-responsive="true"></ins>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({});
</script>
