Refresh saved list not working?

I have modified the contents of a folder that is one of my saved lists.
I don’t think the ‘Refresh’ function is working…

I was expecting to add some files to a particular folder that I have made a saved list out of and then be able to right click the saved list and select ‘refresh’. Then Audiofinder would modify the saved list with the new additions I added to the folder.

Is this how the refresh function is supposed to work?
