A problem with the display of subscriptions

My application is written in SwiftUI, In-App Purchases with StoreKit2. There is a problem with the display of subscriptions on the device. I have added 4 locales: English, German, Russian and French. Displaying the purchase information only in Russian and the purchase process also regardless of the device locale. The application is translated into 4 languages. My developer account is registered in Germany, where I live. How can this be fixed? Thank you in advance
