Guarantee staterooms are generally available to be booked after final payment date (i.e., 4 months prior to a cruise). And these guarantee staterooms are not eligible for the limited time offers - they are considered "last-minute voyage".
I just checked SeatGuru for your flight. It is showing that there are no Premium Economy seats for that specific aircraft. Maybe Iberia changed the aircraft since your original booking. You should definitely try and get a refund from ChoiceAir for the extra money you spent.
