Weird iOS warning: "ITMS-90176: Unrecognized Locale"

Hi! Thanks for this great package. I am trying to use it in an Expo app, and have set up the plugin like so:

[
  "react-native-localization-settings",
  {
    "languages": ["en", "fr"]
  }
]

When I build and submit to App Store, I get this message:

Although delivery was successful, you may want to correct the following issues in your next delivery. Once you've corrected the issues, upload a new binary to App Store Connect.

ITMS-90176: Unrecognized Locale - - The locale names used in localization directories at [Payload/SetlistSherlock.app/base.lproj] are invalid. iTunes supports BCP47 but not the UN M.49 specification. Refer to the Language and Locale Designations guide at https://developer.apple.com/library/content/documentation/MacOSX/Conceptual/BPInternational/LanguageandLocaleIDs/LanguageandLocaleIDs.html for more information on naming your language-specific directories.

When I download the build from EAS this is what that directory looks like:

In Xcode this is how localisation looks after running expo prebuild:

Is there anything I'm doing wrong here? If it matters I'm on latest Expo 52 and using new architecture. Thanks in advance :)
