Background of the issue:
I am trying to clean up old translation data using a new troubleshooting option in WPML located at WPML → Support → Troubleshooting. This is to reduce the size of the *_icl_translate and *_icl_translation_status tables.
Symptoms:
Can't find such option
Questions:
Where is it? What's the exact name for that option?
What does it actually cleaning?
