Ticket Types not showing on notifications

I have an event with 2 ticket types (individual & bundle of 6). The price on the event registration is 0 and the price text is "$40/person or group of 6 for $200".
A Registrant purchased one of each type. The email notification shows the total $ amount, but not the breakdown of the amounts for each ticket type. And it shows $0 for the price and $0 for the Total.  But 2 for the quantity.
How can I configure this event so that the individual ticket type sales are printed on email notifications, PDF invoices, etc.?

Hello

The purchased tickets should be displayed in email, invoices... In your case, maybe it is not being displayed because you have shopping cart enabled on your site? Please go to Events Booking -> Configuration, make sure Activate Shopping Cart config option set to No and try again to see if it works ?
