[Chiuso] export multilingual CSV file

Background of the issue:
I am building a new English-Hebrew business directory site using WPML and Directories Pro. I installed WPML on the original site, GushBook, and migrated from Polylang to WPML. I installed WPML Import Export and followed all the instructions on the WPML site for export and then import (first two taxonomies, and then the business listings).

Symptoms:
The taxonomy export CSV is incorrect (yet the listings are almost perfect). The Hebrew and English taxonomy terms are linked correctly on GushBook, but not in the CSV file. For example, the English business listing category 'Railings' is incorrectly linked to the Hebrew category 'Animals' in the export file. While some export _wpml_import_translation_group values are correct and some fields are empty, MOST are simply incorrect.

Questions:
Why are the Hebrew and English taxonomy terms not linked correctly in the CSV file?
How can I ensure that the _wpml_import_translation_group values are correctly populated in the export file?
