It's possible you used an older version of LeanLocalization which saved the CurrentLanguage as English, so now when you load it it's defaulting to English. You can try building your app again with a new Bundle Identifier, or change SaveLoad to WhenChangedAlt, or call the ClearSave() method when running on your device, then start the app again. Fixed the prefab issue for the next version. No idea about splat binaries. Text is just a string whereas the Objects need to reference something, so maybe splitting them causes the reference to break.
