AdSense doesn't show in header

I created a block called AdSense Header in slot 3 and put AdSense code just created before (the ads is active, i saw in my AdSense).
I chosen Automatic display: Widget for all users on all devices.
I then choose the ads in the widget and saved.
It should appear just near the logo title but doesn’t work.
The strange thing is that if you see the source code of the page you can see the script (from line 154)

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- header2 -->
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-5651622513824744"
     data-ad-slot="8053176660"
     data-ad-format="auto"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

So what’s wrong?
