Enabling Local Reflections causes odd mask effect.

[IRBrainiac]

I was trying to hide the pitguys sunglasses.Mesh Adjustment Hide commands do nothing.Cant hide the ear muffs either.I made the sunglasses textures transparent there and it looked great til I enabled Local Reflections and that mask appeared.Havnt been able to hide that no matter what I do.Only happens with Local Reflections enabled.
The mesh is still rendering from what I can tell.When you can see through the mask you can see the shape of the mesh where it would normally be blocking the ear muffs you can see through to the background.
What is this mask being produced from and why cant I hide the mesh at all?
please help,thank you.

Local reflections on.

Local reflections off.
