I have noticed this for a while over multiple versions.

Looking at the Summary tab on a Windows 10 workstation I see:
Operating System: Microsoft Windows 10 Professional x64 10.0 N/A Build

Inventory Tab:
Operating System: Microsoft Corporation Windows 10 Pro 10.0.16299 N/A
Build 16299

I am guessing this is a bug of some sort as the Operating System info on
both tabs is different and I always have to go to the Inventory Tab to
see the version of Windows 10. Where is the N/A coming from? Bad WMI info?
