AutoCad/Civil 3D 2014 - No Layer States Manager ??

We've recently upgraded to Release 2014, and I use Civil 3D for all my drafting.

We load our discipline specific layers into drawings using *.las files via the Layer States Manager. I've recently had to load a *.las file for the first time. When I open the Layer Properties Manager, I'm missing a few of the usual command buttons in the upper left corner of the Layer Properties Manager.

I don't have; New Property Filter, New Group Filter, Layer States Manager

I do have; Layer Standards, Layer Key Styles, Layer Key Overrides, Load Filter Groups, Save Filter Groups, New Layer, New Layer from Standard, New Layer VP Frozen in All Viewports, Delete Layer, Set Current.

I really would like to Access the Layer States Manager. How do I get it back? What am I missing?

Thanks,

Richard
