Imported contacts succesful but contacts do not show up in Contacts

Imported contacts succesful but contacts do not show up in Contacts

I imported +300 contacts. I can see them in import history. When clicking on a contact in import history I see all the imported contact details for any given contact. So import seems to be successful.

 

However the imported contacts do not show up in the contacts tab. Not in All contacts, and not in a filtered view where they absolutely should show up. The search function also does not find any imported contact.

 

Help?
