You can click the Delete button to delete translation jobs in the following states from Drupal TMGMT:
This functionality is not reversible.
Note: The Delete button is not available in any of the other states, which occur when the job is actively in translation. To delete a translation job that is already in progress, contact Lionbridge Connector Support. For details, see How to Contact Lionbridge Connector Support.
You can delete a translation job from the Job overview page / Jobs tab or from the Job page.
Note: Deleting translation jobs does not delete translated items that have been auto accepted or reviewed and accepted.
