This is caused by a mistake in Data Crow from the past (not the fault of the translators). The field has been translated to "License". You can rename the license field from the Settings > General Field Settings menu option (press F1 from there for more help).
Note, there are two license fields because of the error; only change the settings for the "License" field in the settings, not for the localized license field.
