It will need to have a RealChart and RealCharts need to be enabled. So in the RT picker window there is a RC Column to say if it has a chart, then just right click on the blank track first "Also Generate RealChart" then generate it, click on the RC track eg: RC1516:Soloist and you will see the notes on the neck or if you double click on that track you can see the Tab (Options Show Tablature > Guitar).
