Not fully grasping Post rotation components?

I’m trying to experiment with some of the transform system components: namely PostRotationEulerXYZ in concert with the other related components.

In this example I would assume having these components trigger changes to LocalToParent & LocalToWorld

But in my own use it doesnt appear to affect the final 4x4 matices.
Blue highlights indicate components being affected and changing accordingly(I am just incrementing the Z value of PostRotationEulerXYZ).
Red highlights show no changes where I would expect them? Am I missing components for this to work?

nevermind I was overwriting the localtoparent :roll_eyes:
