Values of multiple checkbox field

when i try to get the value of a multiple checkbox field, i got this:

>> $cbUser->getField('cb_languages');
_UE_LANGUAGE_PT, _UE_LANGUAGE_ES

but i expect to get this:
Português, Espanhol

my language file:
DEFINE('_UE_LANGUAGE_PT','Português');
DEFINE('_UE_LANGUAGE_ES','Espanhol');

On edit form, this values are correct.
How can i get the correct values?

Please see the below getFields API usage tutorial.

If you're using this outside of CB then you likely didn't include CBs language files so it's not able to translate values. Please see the below tutorial on how to import CBs frontend language files.
