Not genereted female and male keys

[yusufkecer]

Hello, the "female" and "male" values under the "gender" and "gender2" objects are not being generated, while the others are being generated without any issues. What could be causing this?

{
    "msg": "{} are written in the {} language",
    "msg_named": "Easy localization is written in the {lang} language",
    "msg_mixed": "{} are written in the {lang} language",
    "gender": {
        "male": "Hi man ;) {}",
        "female": "Hello girl :) {}",
        "other": "Hello {}"
    },
    "gender2": {
        "male": "Hi man ;) {}",
        "female": "Hello girl :) {}",
        "other": "Hello {}"
    }
}

  static const msg = 'msg';
