You can translate directly on the page by enable the translate inline feature. To do this, access System >> Configuraition >> ADVANCED >> Developer >> Translate Inline >> Set to Yes in Enabled for Admin.
After that, your admin page looks different. Hover your pointer over the text, then a little book will appear, click it, then the pop up appear, you can translate the text here.
After you make changes, refresh the page to see the result.
I managed to solve the problem of translation. I had to do it via SQL, because it was something from the database.
I used the following code:
For TAX/VAT
UPDATE `eav_attribute` SET `frontend_label`='CPF/CNPJ' WHERE `frontend_label`='Tax/VAT Number';
For Gender
UPDATE `eav_attribute` SET `frontend_label`='Sexo' WHERE `frontend_label`='Gender';
For Date Of Birth
UPDATE `eav_attribute` SET `frontend_label`='Data de Nascimento' WHERE `frontend_label`='Date Of Birth';
I've solved simply modifying its related value into the database,
table eav_attribute_option_value
Anyway, This is a stupid limitation imposed by Magento community, like other million as this.
