Currently, when copying a page or template with the new “Duplicate (Bricks)” command, this also copies the references to the translations of that page or template (tested with Polylang).
This creates a situation where 2 items in language A reference the same 1 item in language B, which does not make sense and will lead to problems if the uses does not remove the references in one of the two items (original or duplicate).
Proposed solution: When duplicating a page or template, do so WITHOUT the references to their translations (as the plugin Post Duplicator – WordPress plugin | WordPress.org Deutsch (Schweiz) does).
