RSVP is currentyly not active

Hello, I am currently setting up the whole ticketing system, and we have a first event coming up and before our paypal account is confirmed for our association we wanted to use a RSVP and have people pay at the door.

I activated the tickets for page and post, and I setup a proper RSVP inside the page.

Using the new gutenberg experience.

If you can give me any pointers, I would highly appreciate it.

Thanks
