Prepare to be confused.
I have moved all the confirmed talks (and events) to another calendar which only I can modify. That other calendar shows on the public Events page of the website.
The confirmed talks no longer appear in 'WPCA Planned Talks'.
Only the vacant slots for talks appear on the calendar 'WPCA Planned Talks' as 'Talk to be arranged'
