I got a problem on HM GOP config

hi,I have been using HM code to code a GOPsize=16 stream or a GOPsize=8 but coding order is POC 8,4,6,5,7,2,1,3 . to achieve these I modify encoder_randomacess_main.cfg as following :

GOPSize : 16 # GOP Size (number of B slice = GOPSize-1)
# Type POC QPoffset QPfactor tcOffsetDiv2 betaOffsetDiv2 temporal_id #ref_pics_active #ref_pics reference pictures predict deltaRPS #ref_idcs reference idcs
Frame1: B 16 0 0.442 0 0 0 4 4 -16 -20 -24 -28 0
