Comments appearing in wrong posts

Hello!

My blog has a problem in comments, pings and trackbacks: they are appearing in more than one or in unrelated post. This, for example, has the same comments from the previous posts: https://www.heavyyy.com/vampiro/

I guess it has something to do with disqus. I deactivated the plugin but the comments remain in the wrong place.

Anyone has a solution? Or I’ll have to delet all the comments?

Thanks!
