As pictured this new list view has the column headers that are un-clickable, so one can't sort by clicking on the column headers.
Why is the Finder doing this and how do I get it back to the way it is in the deactivated window.
You could also select View > Arrange By > None, press ⌃⌘0, or change the arrange mode from the pop-up menu on the toolbar.

- Click on the menu entry "display options"

An arragement is set on the list view and that is why the directory looks abnormal. To re-enable column header that can sort one needs to first un-set the currently selected arrangement.
A way to stop the arrangement of a list view:

Under Arrange By: pop-up menu select "None".
Now the Finder window should have the clickable column headers as expected in a list view.
