@Dsievers71 - It's not a bug. It all depends on the number of Dragon Medals you have when you go into the fight. Each time you collect 3 dragon medals and you break a tile, your dragon medal count resets to zero. So each time your dragon medal count is zero, the dragon you fight will be Jade. It's only if you save up all your dragon medals and don't spend any to break a tile, will your dragon list be the same as what is listed in this thread and the main Japanese Island quest page.
