Hi there, John!
Yes, I see what you mean. I was able to reproduce the same error on my local setup.
The good news though is that the issue is set to be resolved in the next release–which we should see pop up very soon. I tested this on the forthcoming version and everything appeared to import correctly, including displaying the tickets box on the front end.
Sorry for the inconvenience here–please be on the lookout for Eventbrite Tickets 3.9.5 to come out and let’s see if that clears the issue up for you as well.
Cheers!
Geoff
