[Resolved] Translation File Disorder - WPML Failing to Distinguish Languages Properly

Problem:
The client is experiencing issues with their multilingual website where menus and pages are displaying incorrect languages, and they are unable to import translated files due to an error stating 'Translation job 191 is not yours'. Additionally, the source language in the exported files is mixed instead of being solely in German.
Solution:
We recommend the following steps to resolve the issues:
1) Ensure a full site backup is in place.
2) Delete the translations of the problematic page.
3) Update the page to refresh the translation settings and send it for translation.
4) Download the XLIFF file for the page from WPML>>Translations queue and open it in a text editor.
5) Compare it with a properly translated XLIFF file from your translation agency.
6) Copy the

original="383-7c2b8656b842095c95b2631c872250a8"

code from the WPML-generated XLIFF file's header and paste it into the agency's translated file.
7) Save the file and import it back via WPML>>Translations queue.
8) Check if the page translation displays correctly.
