Quick octaves and moving samples around

I’m a bit confused on how Halion 6 handles different layers. For example if I load a string instrument on a layer, duplicate the layer, and move second layer an octave up from mapping window it doesn’t work how you would think (that I have upper and lower octave playing).

On the other hand, if I select samples from mapping window, copy and paste them and move new set an octave up, then it works how you would think. But still you have just one set of samples (you can see it from memory usage that samples are not in fact duplicated, so further prosessing will affect all samples).

How you really duplicate a layer including samples so you can use then individually?
