Due to the increased workload of localization after the content update, we have temporarily disabled the language options that have not yet been localized. Localization work for each language is still ongoing, and we want to provide the best gaming experience for players in all regions. We will release more language options as soon as possible and hope for your understanding.
The issue regarding languages.
