Hi there!

Thanks for your query.
Would you please check if you have set your Open graph settings?

There are two OG options!

One for Template:

Another for the SP Page Builder:

I would like to request you to check by toggling the options several times! I mean please on one with off another and then back it off with on the other and clear your Joomla and browser cache then check each time.
Sometimes it's only the issue that it is getting the default one somehow.

The Open Graph can be set only for Pages from SPPB, check options in each page.
