It's €15 to cancel the ticket part of the Europa-Spezial fare (I'd assumed this was per person, but I might be wrong).
However, there's also a cancellation fee for the sleeper reservation part of the fare - see details
here. It's "
10% of the supplement, at least €5 minimum", if you cancel at least one day in advance. The supplement for 3-berth deluxe sleeper is €40 per person, so the cancellation fee would be €5 per person; the supplement for a 2-berth deluxe sleeper is €60 per person, so the cancellation fee would be €6 per person. (My previous figure was a miscalculation, based on the cancellation fee on day of departure, which is 50%, and hence €30 per person for a 2-berth deluxe sleeper).

Strange.
A single passenger can book online for one berth in a shared 2-berth compartment, and in theory, can also travel in a shared 3-berth compartment. I was originally searching for one person, and no 3-berth options showed up (indeed, I've never seen bahn.de offer a 3-berth option for a single passenger on a CNL train, although it will offer them for EN-trains operated by ÖBB, etc).
However, when I searched for 3 passengers, some 3-berth options did appear. So, the OP should be able to book online.
