Translate Form Response

I’m trying to translate the contact form Captcha empty response using the PO/MO files, but at the form feedback, it always return “Please verify that you are not a robot.”.

But when i type wpcf7iqfix into the console it seems that everything is fine, since the object returns:

{recaptcha_empty: 'Por favor, verifique que você n?o é um rob?.', response_err: 'wpcf7-recaptcha: N?o foi possível verificar a resposta do reCaptcha.'}

And when i submit the form, it returns the feedback:

{
    "contact_form_id": 114,
    "status": "validation_failed",
    "message": "Um ou mais campos possuem um erro. Verifique e tente novamente.",
    "invalid_fields": [
        {
            "field": "contact-name",
            "message": "Preencha este campo.",
            "idref": null,
            "error_id": "wpcf7-f114-o1-ve-contact-name"
        },
        {
            "field": "contact-email",
            "message": "Preencha este campo.",
            "idref": null,
            "error_id": "wpcf7-f114-o1-ve-contact-email"
        },
        {
            "field": "contact-subject",
            "message": "Preencha este campo.",
            "idref": null,
            "error_id": "wpcf7-f114-o1-ve-contact-subject"
        },
        {
            "field": "contact-message",
            "message": "Preencha este campo.",
            "idref": null,
            "error_id": "wpcf7-f114-o1-ve-contact-message"
        },
        {
            "field": "recaptcha",
            "message": "Please verify that you are not a robot.",
            "idref": null,
            "error_id": "wpcf7-f114-o1-ve-recaptcha"
        }
    ],
    "posted_data_hash": "",
    "into": "#wpcf7-f114-o1"
}
