Looking more closely I see that there is another column, next to the Name column, which does not have a header and the area is completely empty. It doesn't look like there is a way to remove it, like I could with the Unread/Total/Size columns. Trying to manuallly resize the Name column doesn't work as it looks like it detects its the only column and so resizes itself back to the old state. As usual, a picture is worth a 1000 words.
