He already absorbed the Light, Earth, and Lightning Orb. The mutation comes to play when an element orb evolves into a higher tier of the same element category. It didn't matter if the element orb was of second mutation or third; Ace needed them as long as they belonged to the primary element he needed to break into a higher realm. The Yang Orb originated from a fire element, and he needed a fire orb. The same goes for Ice Orb, as it originated from the Water Elemental Oorb. But another elemental orb can't exist at the same time until the previous elemental orb of the same element or mutated orb gets destroyed or used, and this cycle will continue. If you still don't understand it, just remember that the Eight Elemental Orb Ace needs are the only Eight Element Orb that exists in the Golden Sky World, so there is no extra elemental orb in the picture to create confusion. The Mutated Elemental Orbs had their own uniqueness though, which will be revealed in due time. I hope this was helpful!
