concordance with indels issue

Use the supplied Truth region and New vcf as reproduction inputs; first identify the exact bcftools concordance command and version used, which the issue does not include. Compare the indel allele representations and expected first-sample genotype, then define done as a confirmed explanation or corrected concordance result.

I am trying to compare two vcfs, specifically indels and the concordance is incorrect. It says the two vcfs for the first individual are AA Het -> AA Het but it should be AA Het to AA Hom. Any insight appreciated!
