The correct translation for "Type 2 fields" is "Champs de type 2" in the following component :
Key: JavaScdDialog.type2Field (#2) From: trunk\org.talend.designer.scd\src\main\java\messages.properties File
And it's not possible for me to make this correction.
Thanks for spotting this bug on the Babili portal application.
Indeed, the Edit button should be available to all translators (unless the string is validated, but this was not the case).
I changed the FR translation of this string to "Champs de type 2" as you suggested.
And we are in the process of fixing this bug. Sorry for the inconvenience.
And many thanks again for reporting this issue.
