Adjustment of Status - I-485

My wife (F1) and I (primary applicant, H1B) applied for green cards last year. We had our interview scheduled for March 24 2020 in Virginia, which was eventually cancelled. We had not submitted our medical i693 forms, and planned to present them at the interview.

On Apr 20, our attorney received a phone call and an email from a USCIS officer asking him to send our i693 forms and tax documents to the USCIS office in Virginia. The next day, before we could mail our forms, he received another email from the same office asking for my wife's address. My wife was previously located in Virginia but has moved in March to Georgia where I have been located (she filed an AR-11 address change form soon after our interview was cancelled). Our attorney communicated to the USCIS officer about the address change and advised us against mailing the i693 forms to Virginia, since the office in Virginia might not have jurisdiction over Georgia residents. I have not mailed the i693's and he has not heard back from the USCIS officer since.

On the same day, Apr 21, my case status changed to approved and soon my green card was mailed. However, my wife's status remains unchanged from March. So it seems like I was approved for a green card without an interview and without submitting an i693 form, while my wife was not.

Can anybody help explain our scenario? Why was my case approved without an i693? And why was my wife's case status not changed? Is it because of the change in jurisdiction from Virginia? Or is it just a clerical error? And what course of action should we pursue to have my wife's application processed?
