Seat Selection WPF ?

[BrockF]

Have an upcoming flight in J BKK- SYD and seat selection is showing “requested WPF “ below that is “you cannot elect a seat for this flight”. QF Plat and number is in the booking and was able to select seats for earlier flights on the same PNR. Can anyone explain what WPF is? I haven’t had this problem before on numerous EK flights.

Can you get a seat map through something like expert flyer?

1 seat still available and the entire front row all blocked, presumably bassinets.
