Ads are not displaying properly

We were talking before on this same thing and we decided to that we will continue when ads will start appearing on the website.

Now the ads are appearing but they are all showing as a square ad instead of horizontal ads

This is the Gif. See for yourself.
All of the ads are actually horizontal ads but it is visible as square ads. https://blog.iammanpreetsingh.com/
The same code is applied on my main website https://www.iammanpreetsingh.com/ and in that, the ads are appearing fine as you can see in the last part of the gif.
Even in the posts, I added the horizontal ads but they are appearing as square ads.
In the sidebar, it’s fine.

The header ad is going out of the frame for some reason.

Why it is happening?
