Toolpaths not displaying in QT Dragon

I'm pretty new at this so i'm guessing it's something simple. I load the attached .ngc file into qt dragon and I can see what i think are the work piece coordinates, but not the toolpaths, this file does work and draws a circle. I have no idea where/how to configure this, any help will be greatly appreciated, thanks!!

 

What version of linuxcnc are you using?
