AUTOCAD 2015 - DISPLAY PLOT STYLES AND HATCHING

Ok,

So the display plot styles option for layouts doesn't seem to work for hatch objects in AutoCAD 2015?  Is this correct?  Or is it something I am doing wrong?

All other objects display as intented bar the hatching which displays as per its properties.  When I preview the plot the hatch displays aas it should with the plot style applied.

Any ideas?

Thanks in advance
