AOS incomplete after positive interview

[samir182 0]

My wife had her interview on Dec20 for her f21 visa at US Embassy in Nepal and she was approved at the interview and was given a white approval card which says approved and instruction to collect passport. The status on ceac shows Aministrative processing since then and after looking up on VJ, it sounds like normal after interview. 

Now when I log in into ceac on page where we uploaded all our AOS documents and civil documents, the  AOS section shows INCOMPLETE and has 864EZ line item as missing. I already submitted the regular 864 during the NVC process and everything showed completed until after interview. They din't ask for any further documents at the interview or even after interview. 

They didn't keep  any documents at the interview as well beside Medical and kept passport. All the copies of original documents, 864, tax documents and even the passport photo was returned back after interview. I was in impression that they keep copies of civil documents and the tax documents but they didn't and i am kinda confused. May be they just use the scanned copies that we uploaded during NVC??

Is it normal or did embassy mess up something ? May be that can bring impact on the admin processing ? Can anyone who recently got approved verify for me if they have similar situation ?
