drush language importing untranslated strings I am having 2 environments. A staging and a production one. I want all string to sync the strings, so that whenever a new string comes to staging it is available for translation in production. For this reason I've used drush_language module.

Export via

drush language-export-translations --statuses='not-translated'

This provides a .po file where part of it you can see:

msgctxt "tripping_context"
msgid "Giannis test translations"
msgstr ""


When i run an import on prod via 

drush language-import-translations  --langcode="sv"


No new strings are picked up.

Anything wrong I am doing here?
The statuses flag is saying to export untranslated strings, so you are importing an empty file. 
Or are there any steps you missed to describe?
