changing DS160 after scheduling appointment for B2

I created DS160 page for my B2 visa for me and my wife. I gave “Full name in Native language” as my given name surname.
I have scheduled my appoinment for both of us with my wife as primary applicant.
Now I came to know that we(indians) do not have to fill in “Full name in native language”. All my other details are correct.
Please let me know how should I correct the DS160 page, without changing my appointment for me and my wife.

 Can I go ahead with new DS160 confirmation during the biometric(OFSC) appointment.

It should be ok even if you have filled that field.

You can also complete another DS-160 form and carry both forms for interview. Then at the first interview window, let the person know about this and they can guide you.
