[Resolved] Admin users not appearing in “Add Translation Manager” list (WPML 4.6.x)

Problem:
The client is experiencing issues with assigning a Translation Manager role in WPML. Specifically, some users cannot be assigned the Translation Manager role. Additionally, there is an issue with importing XLIFF files, where the error message indicates that the translation job or the XLIFF file does not belong to the system.
Solution:
For the issue of assigning the Translation Manager role, the user deleted the users and recreated them which solved the issue.
Regarding the XLIFF file import error, it is crucial to ensure that the original content does not change after exporting the XLIFF file and before importing it back into WPML. If changes are made to the original content, it will generate a new job ID, causing the XLIFF file to mismatch and fail during the import. For more details on handling this issue, please refer to our documentation here: Handling XLIFF file errors in WPML.
