bgen -recessive analysis - issue with range list

[cgrace1978]

I have encountered a problem when running a recessive analysis with files in the bgen format, I am running the following script, which takes a chromosome, start and end position as inputs:

chr=$1
start=$2
end=$3
sno=$4

/well/PROCARDIS/ukbb_full/scripts/rvtest/rvtests/executable/rvtest
--inBgen /well/ukbb-wtchg/v2/imputation/ukb_imp_chr$chr_v2.bgen
--inBgenSample /well/PROCARDIS/ukbb_full/pheno/ukbb_9922_cad_inter.ag.v4.sample
--pheno /well/PROCARDIS/ukbb_full/pheno/ukbb_9922_cad_inter.ag.rvtest.pheno
--pheno-name cad_intermediate
--out /well/PROCARDIS/ukbb_full/output/ukbb_9922_rvtest_$sno_$chr_$start_$end.out
--rangeList $chr:$start-$end
--meta score
--covar /well/PROCARDIS/ukbb_full/pheno/ukbb_9922_cad_inter.ag.rvtest.pheno
--covar-name pc1,pc2,pc3,pc4,pc5,genotyping.array
--noweb

I am finding that the script fails and succeeds with different range inputs, for example with 5:109517771-125158104 the analysis fails and with 10:60494-7405944 the analysis succeeds. The analysis fails as it cannot find any variants in the region:

[INFO] Loaded 0 male, 0 female and 393461 sex-unknonw samples from /well/PROCARDIS/ukbb_full/pheno/ukbb_9922_cad_inter.ag.rvtest.pheno

Any ideas on what might be going on here?
