[Django]-Django localization: labels don't get updated

I met the same problem, I thought.
But, I just incorrectly stated LOCALE_PATHS setting

Problem seems related to how django finds translation files: see here (django docs). Normally, LOCALE_PATHS doesn’t need to be defined – just make sure your app is in INSTALLED_APPS (which may seem obvious, but isn’t always, for example when having sub-apps).
