HTML issues in posts after import from Blogger

Hi

I imported my blog from Blogger a little while ago.

As i’m updating old posts to fix the featured image and the layout I noticed that in some cases I can’t change the layout.

Here is an example: https://www.orrorea33giri.com/2015/08/la-regina-del-celebrita-eiffel-65-remix.html

I tried to remove all formatting but no luck. i can just remove the picture alright but that’s about it.

I cleaned the cache and cookies just to make sure… I tried to upload different images, move it to the right or centre, but the post won’t change at all.

Any idea how to fix it?

Thanks
