I think that might be bc 兄弟/兄妹(kyoudai) stands for both brothers and brother&sisters; if the translators didn't know in the beginning that the youngest is a girl that explains why they translated "kyoudai" as "brothers" instead
Oooohhh. Thanks!
The only thing that bugged me about this manga is that originally he said that he had 3 little BROTHERS and one older one (in chapt 2), but then they switched it to the youngest being a girl. It's a minor detail, but it was one that I picked up on
