Hey Hugh,
Really sorry to see this – this looks like a bug on our end for sure!
I’ve found the code responsible for the code and will make a ticket for our developers to investigate this a bit more closely. I do not have an ETA on when this will be fixed, but hopefully it will be in the next update of Event Tickets Plus since it’s a relatively easy thing to fix.
Real sorry about the existence of this bug; but thank you for reaching out! We’ll patch this up as soon as possible.
Please let me know if there’s anything else I can help with in the meantime.
Sincerely,
George
