There is a list on the left side of the styles, I think its called All Real Tracks? If you click on that, with "show all styles" at the top center, it should now list all of the styles with the Real Tracks.

If there is something named or clicked in the style filter, you will not get all of the possibilities listed etc . .

Click the "show all styles" button first, then click the Real Tracks list on the left to show ALL of the Real Tracks you have installed.
