ScoreNinja titleText and subboard are not doing anything

Question

I am using ScoreNinja (a high score manager) in my android game, and I want to use the subboard feature mentioned in the documentation.

But when I do this:

mScoreNinjaAdapter.show(score, "Test Title", "test_board");

It doesn't do anything differently. The title is still "Global High Scores" and it is still showing scores from the main board.
