Why does Deezer use US mm/dd/yyyy formate upcoming album releases?

Deezer 9.0.6.3 for Android 

Deezer > Settings >  Country selector is set to France, and my Google Play country is also set to France, but my UI is set to English. All dates for album release dates incorrectly use the US mm/dd/yyyy format

My system language is set to English (France).
