ITRV send to CPC but few accepted

PALASH (Nothing) (2000 Points)

For the AY 2016-2017 & 2017-2018 , 148 ( APPROX ) ITR-Vs send to CPC BANGALORE ( within one envelope 15-20 ITR-Vs approx ) through speed post during 1st week of april 2018 , but during last 2 weeks various msgs are coming to my cell no that few ITR-Vs ( total 16 ) not yet received to CPC BANGALORE till now . I am really surprised to see that within one envelope few ITR-V accepted by CPC bangalore AND rest ITR-V  not yet reached to CPC BANGALORE although both are within the same envelope . 

HOW IS IT POSSIBLE ?
