H1B visa drop box appointment info error


I am on H1B and wife is on H4 visa. We have secured a drop box appointment for next end of November for us both. For some reason on the CGI website, my visa class is shown as H4. I have verified my DS160 is accurate with the correct visa category which is H1B. The ustraveldocs customer service say that we have to cancel the appointment, update the info and reschedule a new appointment(which is very difficult to do at this time).
Did anyone have a similar experience and is it worth taking a risk to go for this appointment? Any help/advice would be appreciated.
