Removing Duplicates from Contact List

I have a SmartSheet grid that has multiple Contact columns using type "Contact List".

There are duplicate contacts shown in User Contact List, which I am trying to clean up.

When I go to "Account, My SmartSheet Contacts", the functionality in that window seems to allow me to delete or edit "My Contacts". HOWEVER, when I go back to the supporting grid and refresh the browser, I do NOT see those modified contact entries.

Is there another Contact List for my grid that I cannot access? Why aren't updates to the name field showing in the grid after editing?
