i can't translate some strings with field translation activated. When i click on edit(screenshot 1) it shows me a textfield "english" instead of "german" (screenshot 2). Typing in something wont have any effect.
My languages are english and german (default language).
When adding a third language (dutch) it shows me the dutch field and i can translate the string into dutch (screenshot 3)
the strings are created by the module drupal commerce and i guess they are field titles.
