Cura 3.6.0 Post Script Processing to Display Layer #

Good Day,
I have a Monoprice Maker Select Plus that I have recently upgraded the firmware to the latest ADVi3++ and I am trying to get the layer number to display on my screen. I have the latest Ultimaker post processing plugin and I am adding the post processing script " Display Filename and layer number". I have left the text block blank. When I slice a file it displays the file name and just the word “Layer” and not the layer number. Anyone have any suggestions to get the current layer number to display on the screen using Cura 3.6.0 slicing software?

Thanks
