Yandex and the insidious image:image. How to be?

Question

Search Engine Optimization

Good evening!
On my sites, I use the WordPress CMS with the All in One SEO plugin for optimization. Since yesterday, Yandex suddenly began to swear in Webmaster (Unknown image:image tag) on ​​a probably incorrectly compiled sitemap (sitemap.xml). All due to the fact that constructions of the form are used there:

<url>
    <loc>https://suvorovski.ru/market_of_delicacies/</loc>
    <image:image>
      <image:loc>https://suvorovski.ru/wp-content/uploads/2017/08/new_ataman-220x162.jpg</image:loc>
    </image:image>
    <image:image>
      <image:loc>https://suvorovski.ru/wp-content/uploads/2017/04/ataman.jpg</image:loc>
    </image:image>
    <lastmod>2017-10-01T19:17:46Z</lastmod>
    <changefreq>weekly</changefreq>
    <priority>0.6</priority>
  </url>

He is not satisfied with image:image. As I understand it, this is a Google tag, Yandex does not accept it. Hence 2 questions!
1) Do I need to fix this somehow, or does Yandex just skip these tags and don't care. If he just skips, then why does he swear at them in Webmaster? Will there be a drawdown in positions because of this?
2) Has anyone solved this problem for the All in One SEO plugin? There is no option in the settings to disable these images.
Thank you!

Answer 1

Yandex does not pessimize sites for image:image. So the easiest way to score on his curses in Webmaster.
If, nevertheless, your hands itch to do something, then you can tinker and remove the unnecessary tag from the sitemap. How to do this you will find for example here: https://alkoweb.ru/yoast-seo-neizvestnyj-teg-image...
