The attribute column is shown (by the little arrowhead) to be sorted in ascending order. However, when a new folder is opened, the file list is not sorted by the attribute column at all - it seems to be sorted by file name. See the first attached image.
Then when I click the attribute column header twice to re-sort in ascending order, the file list order is changed, but it is still not sorted by attributes. See the second attached image.
Note that the first image is the beginning of the file list while the second image is the end of the file list.
