Is og data (title, description, etc.) displayed incorrectly on Wordpress?

Question

WordPress

Hello.
Guys, I ask for your help, I myself can’t figure out what I just haven’t tried.
The situation is this.
There is a site - peru.itinero.travel , it has a module for generating og data, title, description, picture. - it's all right. As you can see, this site is located on a subdomain.
But if you take and share the main domain or any of its pages - itinero.travel/country/bolivia , then og data is pulled by some unprecedented force from the subdomain I described above.
The main site and the site on the subdomain have different admins, but they are both wp.
Please tell me how to make normal og data for these sites, so that everyone has their own?
