Problem which languages

When I launch, for example, "Spore", the game starts in English. When I try to set the local language to Polish (by typing "-L:pl-pl") —the language in which I installed the game—it launches in Portuguese. In the case of German, it switches to Dutch, so the languages are mixed up. I’ve tried everything, from reinstalling the game to changing things in the files, but nothing has helped. Before the launcher update, there was no issue and the game worked properly in the installed language. Please fix this.
