Can't find "Use current layer offset" option with Layer Tool or Layers Panel

I was not understanding how to set the height of a layer using the Layer tool (in a new added layer) other than brush a layer with the Layer tool and reduce the slider in the Layer panel. So, I watched some videos and the online manual and they all mention “Use current layer offset” option that I cannot find anywhere trying every permutation I know.

So, I have the latest version of Nomad Sculpt for the iPad 2.2 and wondering whether this option still exists and all the videos and manual are behind???
