CB with multilingual fields value

Hi to all,
I'm using CB to manage users registration in a Joomla 3 multilingual website.
In user registration form I have a radio button field which value and labels need to be changed when a user submit the form using available different languages.

Regarding the label the problem is solved using custom CB language label but I cannot find a solution for the radio button value.
I tried the same technique as for labels but, using CB login module, instead of language value I see the language label (i.e.: "_UA_MY_LANGUAGE_LABEL");

How could I solve my problem? Can I manage multilanguage field values.

Values don't translate. They're for storage purposes not display purposes so are not relevant to the users language. Only labels will translate. Be sure your select fields have both Value and Label if you need a translated label separate from the stored value. There is legacy behavior where if only a Value is supplied it will be used also as the Label and passed through translations, but I really don't recommend doing this as a short value for storage is better and not dependent on a language key, which should be used as the Label.
