Paper 2D Lighting issue with the Orthographic camera

I have created a 2D platform game level and changed the materials to MaskedLitSpriteMaterial to use lights in the level, but the lighting will only work with the directional light for the orthographic camera. All of the light work with the perspective camera , but not with the orthographic camera? Any ideas on how I can get them to work with the orthographc camera.

Resolved.
