You should be able to cancel the tickets via the app itself, as this is what it says in the FAQ bit at the bottom of the ticket page:
"14. How do I cancel some or all of my tickets ?
You can do this at any time before the event by clicking on 'My Bookings' and choosing the event and the number of trickets you want to cancel."

If you go back to the ticket section can you not see the booking section here, if not then to cancel them you will have to contact Sky so they can do this for you.
