I am working in a multilingual website (French, English, German) with french as default language.
Then I installed the module internationalization + field translation.
Globally, everything works fine. The translate interface is do its job. The issue comes with field labels.
I setup all fields (more than 300) in french language, so the client would be able to translate the labels in english + german through the translate interface (admin/config/regional/translate/translate). Apparently the problem is that Drupal detects field labels as being in english language, instead french as expected.
For example in this picture, you can see that label "surface en m2" is detected as an english text.
This is weird because when I am in edit form page, the content seems detected as french (original text).
Anyone was confronted to this issue?
