求助！JHU金融数学I20上专业信息有误

决定去JHU的金融数学了，前几天收到学校的I-20，I-20上的major处写的是Applied Mathematics，General 27.0301，program length是24个月，但是当时录取信上的major是Financial Mathematics，项目长度3学期。发信问了学校I-20上的信息是不是有误，学校回复是Applied Mathematics is the term that is used by the US government in their method of tracking educational programs. You're still in the Financial Mathematics program. And there's no worry about the length, that's a general estimate and won't affect anything either.
有相同情况的小伙伴么~这个I-20上的信息其实没问题么？
