Workaround
This issue is fixed in WPML Translation Management 2.10.4. Updating solves it on your site, so you only need this workaround if you can’t update yet.
Make sure that you know what you are doing and that you have created a backup first!
Via FTP client or via your hosting panel, try to edit the file in /wp-content/plugins/wpml-translation-management/inc/translation-jobs/helpers/wpml-translation-job-helper-with-api.class.php
Replace these two rows:
global $wpml_translation_job_factory; return $wpml_translation_job_factory->get_translation_job( $job_id, $include_non_translatable_elements, $revisions );
return wpml_tm_load_job_factory()->get_translation_job( $job_id, $include_non_translatable_elements, $revisions );
