In order to register some non-paying guests, I would like to use a discount code that amounts to the fee of the event (i.e. 40 euro fee and 40 euro discount, using a coupon).
On the ticket however, the price of the event is mentioned as it should be, but the pdf doesn't show either the amount of the discount or the total amount (which in this case is 0 euro).

For the same event, members can log in and get their discount automatically: in this case, the discount is 12,50 and the amount to pay is 27,50. All three amounts are shown on the pdf, so the placeholders {TicketsTotal} and {Discount} in this case do their work as they should.

Does anyone have an idea why in the first case the discount amount is not shown? (not showing an amount of 0 might be logical, although I would rather have it otherwise).

Download the Ticket PDF plugin again from our website and install it in your Joomla! installation, we have made some adjustments to correct this issue.

I did reinstall the pdf plugin, but this does not solve the problem. (it only made disappear the image in the body of the automated e-mails after subscription)

In addition to this: the discount and the total amount do not appear in the confirmation email that is sent to the organising party: it just states the fee for the event, discount and total amount are left blank.
It looks like this (in Dutch): (payment related information (if available):
