Remove name from contact list

edited 12/09/19 in Smartsheet Basics

I've created a contact list in which I've entered a few names. When I open the 'Edit Column Properties', I see only the names I want in the 'Values' box. Yet when I try using the list to populate a cell, the list that opens includes my own name along with those I entered in the Values box. Because I can't see my name in the Values box, I can't delete it. Why is this happening? How do I fix it?
