I think this is a bug, the thing is, when I try to change the language of any soldier in the customization menu, the language selector just disappears when I click left indicator when selecting Spanish or clicking on the right indicator while English is selected. Also, I see in the DefaultContent.ini file that seems to exist more packs of languages like British English, Australian English and so on, languages that I can't select in game. Didn't found a post about this issue, if someone knows about this problem, I will be grateful for helping. Sorry for my poor English and thank you.
EDIT: I reinstalled the game and the mod in English and the problem dissapears, however I would like to play it in Spanish, if someone knows how to do it, tell me pls : )
