Some of my contacts are not appearing in my Address Book

[splinternet]

I have about 400 Gmail contacts that I want to export to Outlook 365 (Win 10).  I've exported the .CSV from Gmail and ran the import OK.   Annoyingly, some entries in Contacts are not showing up in the Address Book.  I've tried creating a second Contacts folder and copied all contacts from the first folder, ticking the box which says it can be accessed from Address Book, but it makes no difference.  What am I doing wrong?

It's OK everyone. I've worked it out. Entries in my Contacts folder will only appear in the Address Book if they have an email address. Contacts which only have, for example, phone details won't appear.
