Change y value of actor's transform

Simply trying to alter the Y value of an actor’s location.
I have a reference to my actor (Main Light Actor in attached) and am using an AddActorLocalOffset node and MakeVector node after reading this

Both x and z values should remain constant. When I enter PIE my Print statement correctly shows my values as they should be however when I select the actual actor in my World Outliner I see ALL values are changing!
Is AddActorLocalOffset the wrong choice? Also tried AddActorWorldOffset, AddActorLocalTransform and AddActorWorldTransform nodes with similar results.

Looks like you’re actually telling AddActorLocalOffset to add -1160 to the X component and 60 to the Z component of your actor. Just set those two values to 0 in your “Make Vector” node and only your Y value will change!
