附申EB3被RFE 485J

求问有类似经验的人
lz是EB3附申，家属是主申，家属先交的485，两人结婚后，lz补上了485成为家属485的附申。这都是2年多前的事情了。
后来家属去年先拿到卡。
今年lz受到了rfe，但很奇怪的是，rfe的是485J。感觉把lz当成了主申。原话是：The record establishes that you are the principal applicant of an employment based i-485. In order to continue processing of your case, you must submit a properly completed and signed supplement J, Confirmation of Bona Fide Job offer or Request for Job Portability Under INA section 204J, showing that the offer of intended permanent employment as stated in the Form 1-140 continues to exist...
lz自己的确也有approved 140的，也current了。2年前跟着家属走是因为当时还没有current。
有人有见过这样的事请吗。找了公司的律师了，但回复好慢。所以先上来问问大家
多谢

经常搞错的。请律师写个信解释你是副申就好了
