Common settings in baking not appearing.

Hello, 

I was just about to bake my textures for a model I am working on, but the common settings in the baking window is not showng up. 

Where I select the highpoly model, and edit the distances. Now I have tried to click all the little buttons. and look at any short cuts that may have hidden anything. Please help. I just want to bake my models.

Thank you for your time and consideration.
