White reflection

[devin]

I'm scratching my head trying to figure out why this is happening, as you can see in the window reflection the grey material is reflecting white. I'm pretty sure it has something to do with the physical sun's position but I don't know how to get rid of it. I've tried adjusting the reflection, turning off refraction, changing the glass but nothing makes a difference.

and it's not an override material on the glass that reflects white?
