"Name" folder appears in the top of every finder window I am running Mountain Lion and notice occasionally a weird thing happening in the finder. I will be navigating through folders and notice that at the top of each folder that there is a folder called "Name". I can't click into that folder and there really isn't a folder of that name that should exist. 

I've particularly noticed it when using the column view (not sure what else to call it the view where you see each folder in a column as you navigate through them). It only happens intermittently. Has anyone ever seen this or have an idea of why this might be happening?
I've seen this, can't reproduce it, but it's a glitch in Finder's Arrange By options, and can be fixed by leaving Arrange set to None.
