[Unconfirmed] Lang not translating issue

As per requested, I've opened an issue with a possible problem discussed in Discord.

Not really sure if it's a bug or how to approach this but I've seen this a couple times now. If you have a language that you are supporting and you add it to the supportive languages but ACF does not have lang files for it, it will default all the ACF Lang keys to English, even if you have them overridden in the config file for your language. Any thoughts on an approach to fix this?
