Yes I included the I-797 Notice of Approval, its only one approval notice.

I suspected it could be something to do with the K-2, i will do that

I filed under family based - 2 c 

I am US citizen, I filed I-129 for my fiance & my 2 children and it got approved.

My fiance got the visa K-1 and my 2 children as K-2.

They entered US on 12/10/19 and got married on 01/03/20 within 90 days.

I filed for adjustment of status I-485 and got rejected for improper filing. I included approved I-797 Notice of Action

See the response below, my question is the confusion of what do they want me to file or what mistake did I do

Wife - was principal applicant, Kids are derivative applicants. Their response was as follows on rejection-
