Translations dont work

Hi. I’m using wordpress in PT BR language, but PHP League is still in english. I see that in i18n folder there’s a PR BT translation, but the plugin seems not to recognize it. I don’t have problem with the admin interface in english, but the interface that is shown on my site, I really need it in Portuguese. I need these itens to be transalated: “Pos Team Pts P W D L F A” . If there’s a manual way to do that, please tell me.
