Good evening Jeri and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
We are sorry to hear about your tickets defaulting to 0! We are really sorry for all the inconvenience this is causing.
I would love to help you with this topic.
As a first troubleshooting step, could you please provide us with your system information in a private reply ? (following the instructions found in the link)
If you don’t mind, it would also be great to get a screenshot of the settings for each of the tickets found on that page.
Other than that, in full disclosure, we have a bug ticket for that very issue since it is affecting several of our users).
We are working hard at pinpointing the cause, so any information you can provide to replicate will be greatly appreciated.
Have a good week-end,
Geoff B.
