Win10 C:\ Drive

I have Win10 and if I Open Exploer on the Left Hand Side I can see all of my Drives and USB Drives.
But now I just see my USB Drives and my C"\ Drive is not here.

But I do see This PC and if I Click this I see my C:\ Drive and all my Drives.

And yes I do have my System Folders Set to Show All Drives even Empty Drives.
So what is going on how do I have it Show up in the List of my other Drives on the Left Hand side in Explorer?
