I've been having great fun playing with the WOBP genetic wizard, planning hopeful future pairings... But this one has me stumped.

The pairing I entered is a Vanilla Cream (Vanilla Fire) x Pewter (Pastel Cinnamon), with the goal being to produce more Vanilla Creams, and also Vanilla Cinnamon Fires.

However, this is what I got:
12.50% Fire
12.50% Firemon
12.50% Firefly
12.50% Fire Pewter
12.50% Vanilla
12.50% Cinnamon Vanilla
12.50% Pastel Vanilla
12.50% Pewter Vanilla

Am I missing something? Is there some reason why this pairing couldn't potentially produce Vanilla Creams or Vanilla Cinnamon Fires? Can the parent not pass along both vanilla and fire genes for some reason?
