[Resolved] Translating content from unknown source that doesn't seem to exist.

Problem:
The client is trying to translate existing pages and remove obsolete content from a previous page builder (WPBakery) that is still appearing in the Translation Management filter options, even after deleting all references from the server database.

Solution:
1. To remove a specific string, search for and delete it from the String Translation page. For detailed instructions, see How to delete a string.
2. If there are any unwanted translation jobs, cancel them from the Translation Jobs page. For more information, visit How to cancel translation jobs.
3. To delete templates from WPBakery:
- Reinstall WPBakery and locate the stored templates.
- Delete the templates in the default language and their translations, ensuring to also remove them from the trash.
4. It is advised not to delete template posts directly from the database to avoid orphan records. Instead, consider reinstalling WPBakery or contacting their support for assistance.
