Oci process - correction in application

[kutta]

I submitted in-person the OCI application along with my family at BLS-Canada Brampton br on 20 Oct 2021. After submitting I was rearranged the documents at home. And I found later that I made a mistake by putting my parents as Canadian national. Actually they are Indian National and they live in India. I paid each application CAD 345/- + BLS fee by Debit card $ 8.50. Can any one suggest any best opinion on how to correct and resubmit my application again, would be much grateful
