New sc caste certificate is issued on my old address with a constitutional "9" misses on it..

Hello, I really appreciate what you are doing here for all. I am Kuldeep Kumar from Delhi and recently (on 10/05/2018), I got my new central Schedule Caste certificate for govt job with old address updated on it with a Sikkim constitutional's "9" missing, it is written as "178" instead of "1978". These certificate are issued on behalf of my Original SC certificate issued in 2001, which has my old address mentioned on it. Further, I got this thing rectified from SDM office and it is perfect now on [deleted] with new address and Constitutional "9", which was missed earlier. The Problem is: I applied for Staff Selection Commission (SSC CGL) and now this certificate has to be made on for before [deleted]. I got one before this date on 10/05/2018 with my old address updated and a constitutional "9" missing on it. Now I have other one which had been rectified from SDM office and issued on 08/06/2018 and this is not valid according to their Prospectus. (can I produce this as a Supporting Certificate of my 10/05/2018 certificate ?) My Questions: 1) How will I convince them about this condition ? 2) Can they create any objection on this and if yes then how to solve it ? 3) Do I need to produce both the Certificates made on different dates supporting my 10/05/2018 ? 4) Will they accept it ? Please guide me how to solve this problem, I will be very thankful to you...
