iCal import showing 'not available'

Hi,

I’m using the ical export function to import bookings into my icloud calendar.
The problem is that ‘not booked/non-available’ dates show up as ‘not available’. This is very annoying as I would only like to have ONLY the bookings show up. Is there a way to ‘turn-off/hide’ the other ‘not available’ dates?

i.e. I also synchronize ‘national holidays’ and would not like it if rest of the year it show ‘non-holiday’.

Hey, did you ever find out how to prevent this?

Thanks in advance
