@VigneshViky: Where did you purchase your phone from? It may be the case that it was intended for use in a country where French is the native language, which may explain why the Members app is defaulting to French. Try heading to Settings > General Management > Language, and make sure that your native language is number 1 in the list, or remove French from the list, if applicable, to see if this helps.
