OG:image -metatag works differently in production

Hello!

We are trying to get the first image of a blog post and the first image of any thread (if exists) to work as the content for the OG:image -metatag. If I have understood correctly, Khoros should do this if I have a certain setting on in studio or admin? 

Currently, I can see the metatags working correctly in our preproduction environment, but not in production. I only have permission to make changes in the preproduction studio, so does anyone have ideas which setting might be different in production? 

Both environments have the Node image URL set in admin / open graph, in pre production, the tag gets written over with the correct tag, but this does not happen in production. 

Other metatags (OG:url, OG:title etc.) seem to be working in both environments.
