I'm using dev version from 8th of January and i18n 7.1.4 and Views 7.3.1

The only way I can translate field labels is via Translate view button inside Views UI.
Otherwise, the translation made in content type management does not show in a view.

It's not clear for me if it's a general bug or if it's supposed to work.
Can someone clarify?

I activated Translate view button inside Views UI.
I added filter : Traduction du contenu : Langue (= Langue de l'utilisateur courant)
I leave default value for advanced config : Field Language:Langue de l'utilisateur courant
I activated drupal empty cache.
In /admin/config/regional/translate/i18n_string, I also activated Views and fields refresh.
what else?

Can someone clarify the actual situation?
