It isn't grammatically incorrect. "Their" can refer to one or multiple people in a possessive sense the same way "they" and "them" can refer to one or more people. "They/them/their" is used when no gender is specified, but the antecedent is not an object and can't be referred to as "it". It's a neutral pronoun, which is shorter than saying "his or her", and is more acceptable in the modern PC-ness.

It is probably, however, an incorrect translation.
