OK, what I would do is turn off spot and two of the points and see if you get shadows.  it seems like the lights are wipeing out the shadows.  I assume that one of the points is above the torch.  Set it with some type of falloff(defined, linier or invers square) and then add and modify one light at a time.

I include one I did three years ago as an example of one light.
