After the data are set to the appropriate Load Modes, simply Refresh to see the data. If you want all the tracks to display at once, use the Refresh button in the Data Access panel or the refrtesh icon at the top of the window. Alternatively, if you want to visualize one track at a time, use the individual refresh icon next to the tracks.
You might partially load a track (Region in View, Autoload) and then zoom out to show a greater region of the data sets. IGB will show gray in the area of any track that is not fully loaded.
