It looks like you already got it taken care of, but for anybody else that may have the same problem...we got both NOA appointment notices for biometrics for her AOS and EAD on the same day. The EAD notice had her middle name misspelled, but the AOS notice was correct. That tells me that it was somebody manually typing them in and not automatically generated. We didn't even notice it. At the biometric appointment, they noticed it, and corrected it on the spot.
