When duplicating a translated entity, the new node's content_field (or any reference field) still references to the same paragraphs as the original one.
1. Translate a node (eg. EN to FR)
2. Replicate the original node (EN)
3. Remove the FR (clone) => your node won't remove, the paragraphs inside field_content will be gone or check the database for duplicate references
