Reflections view mode white

Hi,

I have a problem understanding reflections in UE4. I have inserted Sphere Reflection Captures in my scene, baked lightmaps and tried updating my reflection captures but whenever I view my scene through Reflection view mode everything in my scene is white. What am I doing wrong?

Ive just ran into this problem. Any idea what causes it?.. Actually I just realized if you reset your view mode stuff to default it fixes this.

I exited game mode which fixed it for me.
