Adjustment of Status - I-485

I was filed for by my US wife in October 2017. Got EAD in May and interview in Octber 16th. Another interview on November 19th. This time ,we were repeated and it was strokes but named " SWORN STATEMENTS '. We spent 6hours,three hours apiece to be grilled by a woman. More than 100 questions were asked and we answered them correctly except some few . She made us sign the statements but never asked us questions on the few discrepancies. On 28th of November,she sent us a NOID for my wife's i-130 for lack of sufficient bonafides. Saying we don't have enough evidences and that we should respond within 30 days or be denied. I am black African and my wife Chicano American(huspanic) BORN here in US. Even her mum and grand and great grand parents were all BORN here. We presented our lease agreement, insurance for cars,photos of our one year anniversary in Las Vegas, same club membership cards, phone bills,bank accounts ,referrals from neighbours and church, and we live together but she still wrote us a NOID.
Who has had this kind of experience? My lawyer accompanied us to second interview . He says he will respond to the NOID but I am asking : who has got this experience before? What chances do I have?( My marriage is genuine). I believe that if the immigration officer made a discreet investigation into our case,she will know we are genuine but I think she just hates me.
What do I Do? What chances do I have? Invase,she denies it again,since the same NOID answers goes to her table,what should I Do? Replies will be appreciated.
Thanks
