I had problems also when adding it - it was added 3 times along with a Charity Drive event. I can't delete this, so could you just delete all the entries ths up when you've got a minute - I'll add them back later. Keep it low priority list.
I know. It's a bit shot at the moment. I need to do some work on it and migrate it to another database at the same time. I'll try to sort that next week.
