Hi w,
This might help.
Firstly, to see what MIDI Supertrack sets you have, it's possible to...
1. enter into Stylepicker
2. select "Other" (#1) on image
3. select "Specific MIDI Supertrack Set"
There are currently 27 sets. With the Windows version of the program, this is not working correctly for me at the moment so I recommend the below approach as a double-check.
Alternatively, click on the heading at the top of the "Set #" column. This will sort the column. Then just scroll down to see what your highest MST number is. (This is the method I use.)
The link below will take you to all the currently available MST sets that are available.

P.S. If it helps, my latest MIDI Supertrack is 3013: Piano, Rhythm CelticSlideFastJigDave Sw 140 (that's from Set 27)
