Hi John,
It looks like you might be missing some Realtracks that are part of the style.
When I had a look at what Realtracks were in Set #178, I obtained the following list. (It's an amazing collection!)

The above style you tried also uses Realtracks 1791, 1792, 1795 from Set #162. Only the track #1976 belongs to Set #178.
To get this style to load with all Realtracks, it's also necessary to have Set #162.
For what it's worth, Styles have no control over the way a Realtrack is played. It is simply a way of grouping a particular collection of Realtracks together. To this end, you could add any RT that suits as a substitute for those from Set #162.
Hope this helps,
Noel
