The OpenGraph tags are automatically generated from the meta tags. In order for me to be able to advise further, kindly share with me a related URL to the affected page using a sensitive data section so that I may be able to advise further.
Your page is missing OG and meta description tags. We might need to take a closer look at the settings. Please edit the first post on this ticket and include your WP logins in the designated Sensitive Data section.
It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:
This problem is happening because the Open Graph image that you have assigned on the Titles & Meta is too small and thus causing the og: image to miss on your pages.
You need to assign an image that is at least 600x315px. Recommended size is 1200x630px.
To fix this, I have temporarily used one of your gallery images as the OG image on your homepage.
