I’m having trouble using Asset Groups for localizing audio assets in UE 4.25 and 4.26. I want the user to be able to select the text language and voice language as separate settings.
When my culture/language is equal to the Audio culture then the correct localized assets play (for example, if all three are set to “de-DE” then I hear the German audio assets).
But when these settings are not equal to each other then I always hear the English audio instead (for example if language/locale is “ru-RU” and Audio asset group is “de-DE” then the non-localized English source audio plays). In this case I also see some warnings in the log that may be related:

I am testing it in a standalone packaged build.
More details:
I have created an Asset Group for Audio based on the documentation, in DefaultGame.ini I have:
[Internationalization.AssetGroupClasses]
+Audio=SoundWave
+Audio=DialogueWave
+Audio=DialogueVoice
+Audio=SoundCue
And in DefaultGameUserSettings.ini I have the following (because the setting doesn’t get created by the Kismet library otherwise)
[Internationalization.AssetGroupCultures]
+Audio=en-US
I am using the Kismet localization library to update the settings from C++, based on selection from UMG widgets, like this:
For text language:
UKismetInternationalizationLibrary::SetCurrentLanguageAndLocale(GetCultureFromDisplayName(SelectedItem), true);
For audio language:
UKismetInternationalizationLibrary::SetCurrentAssetGroupCulture(FName(TEXT("Audio")), GetCultureFromDisplayName(SelectedItem), true);
This works fine in terms of updating GameUserSettings.ini, but results in the above-mentioned problems when trying to play audio.
I’m hoping that I am missing something obvious
