Hi David!
Thanks for reaching out to us! Let me help you with this topic.
I could not reproduce any of those issues you are having in my local installation. Could you please share with us a link to the event where you are experiencing the first issue you mention?
Also, this could be related to a theme or plugin conflict, so to narrow the problem down please go through the steps provided in the testing for conflicts guide > https://theeventscalendar.com/knowledgebase/testing-for-conflicts/ and let us know what you find in the process.
We have added attendee information fields to the registration form and none of it is being included with the subsequent emails.
Please note the attendee information will only show up in the ticket email that gets sent to the user. The WooCommerce order emails do not show this information by default. However, we do have an extension to accomplish that > https://theeventscalendar.com/extensions/add-event-and-attendee-information-to-woocommerce-order-details/
Please let us know about that.
Thanks,
Victor
