Character look and feel changes with Scene Light On/Off

Hi,

I have downloaded Character from AssetStore. While using this character, it looks different with Scene Light On and Off. Attached are the images of the character with Scene Light enabled and disabled. The look and feel of the character especially on the face, completely changes with enabling and disabling the SceneLight. I have disabled the Cast and Receive Shadows on the Skinned Mesh renderer. Also disabled the shadows in Quality settings.

Why is this happening?
