ApiAiSDK.SupportedLanguage.FromLanguageTag(Language) doens't works

[newrochelle]

SupportedLanguage supLang = ApiAiSDK.SupportedLanguage.FromLanguageTag(Language);

supLang is always equal to "en" even if Language is "French".

i'm using version 1.6.5 of ApiAiSDK

below "SupportedLanguage" class (from metadata): /********/ namespace ApiAiSDK { public class SupportedLanguage { public static readonly SupportedLanguage English; public static readonly SupportedLanguage Russian; public static readonly SupportedLanguage German; public static readonly SupportedLanguage Portuguese; public static readonly SupportedLanguage PortugueseBrazil; public static readonly SupportedLanguage Spanish; public static readonly SupportedLanguage French; public static readonly SupportedLanguage Italian; public static readonly SupportedLanguage Dutch; public static readonly SupportedLanguage Japanese; public static readonly SupportedLanguage ChineseChina; public static readonly SupportedLanguage ChineseHongKong; public static readonly SupportedLanguage ChineseTaiwan; public readonly string code;

    public static SupportedLanguage FromLanguageTag(string languageTag);
}

} /********/

How can I fix it?

Many thanks in advance.
