The same mutation in two different gnomAD sub populations

Please, could you help me with this question
Today, I noticed something which I want to share here:

I extracted mutations in these coordinates

7:140476600-140480852

7:140922446-140926601

7:141013033-141016000

7:141550400-141552801

7:141736785-141740201

from gnomAD non_cancer_nfe & gnomAD biobanks_nfe sub populations, independently, but I got the same number of mutations in both of gnomAD non_cancer_nfe & gnomAD biobanks_nfe sub populations.
I have not been able to figure out how I got the same number of mutations from 16k controls_and_biobanks_nfe and 74K non_cancer_nfe from gnomAD v3.2.1

Any idea please?

Thank you in advance.

These two datasets overlap.
