I usually vary the languages of the Calibre interface and I am noticing that I can choose two languages of Spanish.
Checking on Transifex, it may be Mexican Spanish, but it surprises me because it is not yet available for use.
And that is precisely the difference I notice. If I choose one there are translated words and if I choose another there are not.
Would there be a way to name the language differently?
Example:
Spanish - Spain)
Spanish - Mexico)

Although it seems redundant to me, because if each Spanish-speaking region decided to translate Calibre we would have so many Spanish languages per region.
