This happens sometimes ... I had a client who had an NOL to carry back and we sent 3 amended returns ... 2 processed immediately with no issue and the last one required extra correspondence for info that was already on the other returns that had been processed. No rhyme or reason sometimes ... probably processed by different people instead of all 3 by one who would see the entire picture ... even sent them all in together in individual envelopes in the one larger envelope and even marked on them process this one first , second, third ... still didn't help.
