Registering for GRE in Nov 21

I am trying to register for a date in Nov to take the GRE but I am not seeing any options for at-home or test-center option. Is there a bug in the system or is it possible no more slots are available for November?

Anyone else facing this issue?

If you see available slots for the December, then I don’t think it is a bug. My hunch is that all available seats for November are booked.
