TOPIC: How to show date registered?

In the "Admin -> Configuration -> View Registrants" tab is an option to "Show Date Registered". When I check this "Yes", nothing seems to change. I am expecting the date registered to show up on my frontend Attendees list but it does not. I find the same is true if I click "Show Username".

Am I missing something with how this is supposed to function? This is with 2.7.3 and 2.7.4.
