Yeah no, it is definitely in the grip function, you need to pass in the transform of the actor you are gripping, not the transform of the motion controller, if you want it to snap to the controller then use a “MakeTransform” node and leave the location as 0,0,0 and tick the “Is already relative” checkbox, but you will need to fill in the Scale part of the transform with the scale of the actor you are trying to grip.
With how you currently set it up you are creating an empty transform with only a location set so it is defaulting the scale of the gripped actor to 1,1,1.
I allow it to change the scale of the gripped actor specifically because it is handy sometimes to say add a 25% scale increase to held items (papers/tablets/ect).
