Why doesn't Facebook process Open Graph tags?

Question

Facebook

When scraping any page on the alif.tv site, the Facebook repost debugger says that it finds Open Graph tags, but shows them in the "Show all raw tags" section. And in the section "We created the following Open Graph properties based on raw tags" lists all the same, with the same values ​​that are set in our tags, but sometimes does not catch og:image (example: https://developers.facebook .com/tools/debug/sharin... ) Tell me,
dear colleagues, what could be the matter?
