H4 dropbox not accepted at OFC as no prior Visa for dependent

I added by dependents as family and took DB appointment as I was elligible for Interview Waiver program. However, at OFC they informed me that I need to take separate appointment for my Wife as she doesn’t have any prior Visa. Post that I will have to take appointment for my Son as Both parents Visa should be present. But I have already made the payment for all 3 of us. Now it is again asking for making payment for taking new appointment. Any guidance on this is much appreciated. Thanks !

Ask the usatraveldocs support if they can attach the payment receipt to a separate account or let you use it for spouse’s appointment.
