Hi Steve,
Thanks for reaching out!
I did a quick test on my end and was not able to recreate the issue. Could you please send me a screenshot of what you are seeing on the back end edit screen and the front end? Could you also please share your system information with me?
My first thought is that you might be using a saved ticket fieldset that has an empty space, so that would be something to check as well. If that is the case, try deleting the space from the saved fieldset under Events > Ticket Fieldsets and see if you still have this issue.
Let me know how it goes!
Thanks,
Jennifer
