Travelers Mile Luggages review for Geolocation

I don't know if it's something I am not getting right. I installed the app, then goes to vmy website to give it a try on what customers will experience. Unfortunately when I choose a language, the only thing that changes is the theme language. Contents such as text, product titles etc still stays in English bwhich is my store default language. So I wonder how this app is of help to customers speaking other languages. Is there a way out?
