So Knov and Sayird don't use Conjuration, Morel doesn't use Transmutation, and Hanzo and Biscuit doesn't use Manipulation.

It makes more sense that that's just Conjuration and it's no big deal for them because Transmutation is next to it. Transmutation is supposed to affect aura and nothing else. Creating an object by sacrificing another object is still creating an object. This is why Hinrigh, Tsubone, Kurton and Padaille are Conjurers.
