If she has EAD take it with u, and other Org/copy 485 receipt and other doc that clearly says name+A#.
Request them to Correct it when u go for FP. they would. Every FP has bar code so if have received on correct addr, and if ur receipt of 485 has correct name than don't worry. send one request to TSC-USCIS for correction along with copy of FP.
but never missed the FP done just becz of that.
after sendind letter for correction, also call on 800 no and there is an option for type / error. option if u find than fine if not , don't worry talk to TSC- directly. read other prv threads to learn how to connect TSC direct , if u don't find post again.
Good Luck
