Hi,
Please install and active yoast seo plugin.
and check this guide to config
If you’ve updated your social settings or metadata for an article and aren’t getting the right details in Facebook yet, you might need to force update Facebook’s cache of that page. To do that, go to the Facebook debug tool, enter the URL you wish to update and click scrape again.
If it doesn't work, let's send me your website managment information ( admin url site, username and password ) in order for me to have access to know the exact issue. We will take it a lock on this help you.
Best Regards,
