This isn't a problem: Google Play does not let users know what languages are supported by your application and it may be that some of the libraries you use (such as Google Play Services) are localized in 55 languages and users would see those translations based on their language, even if the vast majority of your application is not translated.
The only way for a user prior to installing the app to know what languages the app is optimized for is if you add a translation on the Store Listing tab.
