NVC Checklist - sent in response and get ANOTHER Checklist

[USCHE 3]

We sent in our updated I 864 to the NVC and they received it on Monday, 23 of March. Today, 25 of March, we received ANOTHER checklist asking us to send in the updated I864 A with the adjusted gross income change as well. In the first checklist they told us NOT to send it to the NVC and that the principal applicant must bring it with them to the interview.

Should I fight this or pay another US$60 to send in this one form? Anyone else have this issue?

In my haze of frustration, I read the response from the NVC incorrectly. It says it is still missing (obviously because they told me not to send it with our response), not to send it in but have my husband bring it to the interview. I think this means our case is complete? Do we get any other notices or do we wait for the embassy? How long does it take for them to schedule an interview?
