Hi Phil,
just had a look, and I can only see one event in the future apart from the one on the 18th - that one event is on 6 July. There are no other ones in the system for you.
Without knowing what you did, and what was there before, I can't be certain as to what happened. The only thing I can think of is perhaps the other events you are thinking of were recurring events? Did you create them or did some one else (Michael Brown perhaps?)
(Actually I just checked and Michael's last event was in Dec 18)
