Thank you so much for your response! I did go through all of the Verify/Rebuild steps as you outlined below, and was disappointed to see that it made no change; we still do not have the sort option as pictured in your screen shot.
This has been a source of frustration for about a year. Nothing we try seems to fix this issue!
I do appreciate your effort to help us - I will keep looking for the answer to this puzzle.
