Doesn’t work Open Graph

Hi!

1) On three pages of the site, including, on the homepage, Open Graph does not work properly:

https://hbd.su/page/partner/main

https://hbd.su

2) On any page of the site, if you assign it to your homepage, Open Graph does not work properly.

I’ll show how the problem is demonstrated in the Open Graph Objects Debugger.
