Missing :locale fields in the new record

[modreoci]

I did everything what is in the documentation properly. Everything seems to be OK. Records with the existing translations are updated correctly, but the new records (SQL commands) are without field :locale and cause the error message:
- Translations locale can't be blank

Here is the output (server log):

And finally the screenshot (both translations fields Name was correctly filled out):

Hi @modreoci, did you manage to get it work? I am facing the same issue.
