Good afternoon Geoff and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the field not showing up on your tickets. Yikes!
I would love to help you with this topic.
In fact, the normal fields are not showing up as well.
As a first troubleshooting step, could you please provide us with your complete system information in a private reply using the instructions found in the following link?

Secondly, could you tell me what is the start sale date of your RSVP tickets ?
Have a good weekend,
Geoff B.
