Contact names not email address
I have a lot of contacts in My Smartsheet Contacts but recently when sharing new sheets etc with my contacts it is displaying their email address and not their name. Its only a minor thing but is one that is really annoying me as i prefer to see their proper name only. it is only affecting some of the names and not all of them so i am unsure of what i have done wrong !
How do i get it to display their proper names and not the email address, please.
