I subscribed to EF and indeed these days were Z0 or Z1, but showed as available for 2 on the AS website. 24 hours after my failed attempts at booking, these still all show as available from AS, so if it is a synchronization issue it has a long cycle...

If you are planning on transferring to AS/buying miles/etc for an award, be sure to double-check what the website is showing via EF beforehand!
