BTT / Golden Chaos / iCalBuddy

Hi! Very pleased with BTT, I'm trying right now the Golden Chaos mod. It's very good.
I have one little issue, and can't go through (had a long time on google to find a solution).
The issue is more a Mac OS issue for me, with iCalBuddy.

On the Calendar part, the first event is a "ghost" event found by Siri with natural language in mail. I can't exclue this calendar event! How can I manage it???

I don't want to see these natural language events.

Sorry for my bad english, and thank you for your help!!!
