Langauge issue

[etxeberria]

I`ve created Bretagne(Brittany) as a separate nation suing east germany, everything works just fine except all Bretons (i have changed the nation of all ppl born in Brittany), speak only Breton. I have set 100 to both french and breton in the nation. Still regens only speak Breton, if i set french langauge as the language of the cities than i get regens with second nationality as french, which i don`t want to.

Edit. Never mind i solved it, problem was in local regions settings.
