not giving unique values when doing intersectBed between VCF file and BED file

[AA D]

hey I am facing this issue any idea why?So my vcf contains these :

chr1 201784568 . T A . . DP=12;MQ=60.00;TLOD=5.06;FractionInformativeReads=1.000 GT:SQ:AD:AF:> chr1 201785282 . CTTTTT C . . DP=123;MQ=60.00;MQRankSum=8.531;ReadPosRankSum=0.518;TLOD=4.43;Fract> chr1 201785282 . CTTTTT CT . . DP=123;MQ=60.00;MQRankSum=8.531;ReadPosRankSum=0.518;TLOD=9.28;Fract> chr1 201785282 . CTTTTT CTT . . DP=123;MQ=60.00;MQRankSum=8.531;ReadPosRankSum=0.518;TLOD=4.38;Fract> chr1 201785282 . CTTTTT CTTT . . DP=123;MQ=60.00;MQRankSum=8.531;ReadPosRankSum=0.518;TLOD=13.77;Frac>

when i intersect  it with the bed file i had obtained after sorting from the below cmd:
sort -t $'\t' -k1,1 -k2,2n k75.bed | bgzip > k75_sorted.bed.gzThe intersect cmd is:
cat <(grep "#" Horizon_44799.HD827.hg38.raw.other_variants.dragen.vcf) <(/usr/local/mrgstorage/software/BEDTools/bin/intersectBed -a Horizon_44799.HD827.hg38.raw.other_variants.dragen.vcf -b k75_sorted.bed.gz -u ) > test.vcfwhy am i not getting the unique values in test.vcf though I use -u
