Volumetric Clouds 4.25 question - Details 2?

Silly Question, but in the 4.25 BP_Volumetric_Cloud, where are the Cloud Detail 2 and Cloud Detail Amount 2 settings hooked up, as they do nothing when I play with them in Details Panel? Is this just a leftover where they were going to allow more layers? Or is this something I can tweak somewhere? In one single BP is it possible to have 2 or 3 layers of different noise?
