Hi Andy, this is not a bug and is explained at the top of the tySplineMesher docs.
All spline variation/random parameters are seeded by the material ID of the underlying splines. Set your base particles to have a random mat ID and you'll see that all elements in your list are then used.
The reason for this is because max doesn't really have a way of setting or tracking subspline IDs...so in order for consistent seeding between frames and such, I have to use a baked parameter like material ID.
