The Hide Unconnected Pins option in the Get Class Defaults node no longer hides any of the pins.
Tested in //UE4/Release-4.25 @ CL 14469661 and this did not occur so marking as a Regression.
**Hide Unconnected Pins doesn't hide the variable pins on the Get Class Defaults node
The Hide Unconnected Pins option would hide any pins that aren't connected
