Apologies for the inconvenience.
At the moment, this is expected behavior rather than a bug. When SP Page Builder content is used inside Joomla articles, SEO-related metadata (including meta tags and Open Graph tags) is not handled by SP Page Builder. Instead, Joomla’s native article system or other SEO extensions are responsible for rendering those tags.
Because of this architecture, SP Page Builder does not override or inject meta/OG data at the article level, and there is currently no planned feature to change this behavior.
We appreciate your understanding.
