invalid link to export calendar

[Megan105]

I am exporting my airbnb listings to sync with my bookings.com calendar and for one listing no problems. For the second the link show as invalid. I am copying and pasting directly from the airbnb exported calendar so cannot see why there would be an error. Any experience with how to fix this? 

Airbnb support is now harded than ever to contact. No links to open chat or send email visible from the help center. Customer service seems to have gone downhill/ be none existent these days...You are my only hope!
