Fysal Hi, this warning is appearing due to a recent Google update: https://www.seroundtable.com/google-video-is-not-the-main-content-of-the-page-36539.html
As covered in the article, any site which has 'A blog post where the video is complementary to the text rather than the primary content of the page' will see the warning. I do see your site is using floating videos which could explain the Console Warnings. You might want to try disabling the floating video if the console warnings worry you, but if disabling that option doesn't resolve it we can contact the Humix team since all other videos are disabled on your site.
Additionally, can you send us a couple of the affected URLs from your domain?
