Singapore Airlines KrisFlyer - A380 Upper Deck seating

Does anyone know if there are any seats in front of row 81 AC or HK?

The seating map below shows there is row 80, but there are no seats in that row on AC & HK:

Doesn't have any seat in front of row 81 AC and HK... there may be some error..

I believe row 80 only applies to the DEFG section.
