I agree entirely that the field ‘Issuing Entitly’ should not be used for issuing banks in the banknote section. Unfortunately, the field of ‘Issuing Bank’ cannot be added to.
I will update Issuing bank for Polish banknotes with National Bank of Poland throughout, as I add other edits.
[I see you have updated ‘Issuing Bank’ for Finland also, way ahead of me, I was about to post a request ;)
Thanks]
