How to make a change label of a candidate search filter.

Hi,

we would like to make a change label of a Candidate search filter. In particular, we would like to change the label 'Sito di offerte di lavoro interno' which is one of the available values for the filter 'Source' of the 'Candidate details' section in the Candidate search page (see the screenshot 'Sito_offerte_lavoro_interno.PNG' that I attached). I tried to follow the standard procedure, namely I searched for my label, 'Sito di offerte di lavoro interno' , using Text User Interface, but I did not find anything.
