It isn't. For some reason, they translated proper nouns in this course. My wife, whose name is Maria, does not suddenly become "Mary" when we're in the US. That would be totally absurd.
I genuinely don't know why they did this, as no one does it in real life except people who have names that are extremely difficult for foreigners to pronounce, like Chinese immigrants. English speakers have no difficulty pronouncing Romanian names or vice versa.
