og:image:type" is missing only on a few posts

Whenever I tried to share some posts with direct link on Facebook the post image was messed up (it was added the default one from the homepage). I fetched via the Facebook tool and it has shown og:image:type" is missing error. I checked the source code of two different posts (one that was working properly and what that wasn't) and find that og:image:type" is not present in the post with error. Now my question is why at some posts is present and in some not? I am using Wordpress on this website and the Yoast Seo plugin.

Nobody used to have similar problem?
