Contact names in contact list

I have a list of contacts in my outlook.live account that are listed in numerical order by office number, e.g. “101 Larry” “Smith” is the first and last name for Larry Smith in office 101. This method has always resulted in a perfectly numerically ordered contact list, until recently. Now, when I add Larry to my contact list, Outlook only shows Larry’s email address, no name, no office number.

Any help / suggestions would be so greatly appreciated. I’ve tried using customer support before, not looking forward to that ordeal again.
