I've tried various settings but I can't seem to get any 'cancel' button to show on the front-end.
I've got the "Booking-Cancellation till (days)" set to 5, and I've got a booking on an event on 5/22.
We're using the 'modern' layout.
I have the following buttons on the details page:
Contact, Calendar file, Print, Participants, Book now, Your Booking details
On the Booking details page I have:
Print, Calendar file, Contact, Invoice, Ticket

Should I be looking for the button somewhere else?
Or is there some other configuration that controls a cancel button?

I'm using Matukio 6.0.4
Joomla 3.5.1
PHP 7
