Honestly, Latin American support for Age 1 DE is defective and full of flaws. I recommend using my mod to fix it. The language support in Age 2 DE improved, but it’s far from being perfect, too.
The 3rd DE will probably be best if only includes the Spanish from Spain language, as I don’t want both of them to be low quality and inaccurate; one good translation is better than two that aren’t.
