Majesty 2018 piezo switch reversed

So I just bought used Music Man Majesty 2018 in arctic dream finish and it seems piezo switch is reversed. So when switch is in position 6 (pointing at me) magnetic pickups are on and in position 4 (pointing at neck) only piezo is on. Otherwise guitar is in great shape and plays like a dream, but this kinda bugs me. Is it difficult to fix or does it cost much?
