Some instruments extremely soft in Finale

Recently I installed Finale on my Linux computer using Wine. While the application itself works correctly (i.e. I can edit music scores), the Garritan Human Playback sub-application is having trouble playing instruments at the correct volume. For example, cellos are barely audible.

Is there a way to fix this, or do I need to just live with it?
