Issue about partition result

[YuChrming]

dear professor, I was assembling a triploid genome.The input of allhic is from hifiasm, *.asm.p_utg.fa which is without "bubble". Runing the partition step, weird results were found. ALLHiC_partition -b prunning.bam -r *.asm.p_utg.fa -e AAGCTT -k 3 The results are identical either I setting the parameter 3 or 17 , why? Cluster result show that nearly all the contigs(3300+) devided in one group, while residues were in 16 groups and less than 200 contigs in total.Is it normal? Thank and expect your response!
