This train has a very complex story it seems.
.
Reserved Tickets are available from Delhi to Visakhapatnam with train no. 12722 only, NTES shows this train as 12862, probably because it cannot show two different trains having same number (for the benefit of tracking).
.
The...
more... UnReserved Coaches in this train are added at Kazipet, and the Reserved ones come from Delhi. So, the Coach Composition should have only the UnReserved Coaches.
.
I think you can void this. Technically, the CC of 12862 should be just the UnReserved Coaches, as they are the ones running with the particular train number.
