Possibly a stupid question: When I sync from Zoho CRM to Campaign, should I see those contacts in the Contacts list on Campaign?

I have just initiated and completed a sync of my existing Zoho CRM contacts over to Zoho Campaign.
It seems to have completed and synced around 500 contacts.
However, those contacts do not appear in the All Contacts list (or any other list that I can see).
Is this correct?

If it is, how do I segment those contacts? I have set up a segment with the criteria I wish to apply, however it tells me there are 0 contacts in the segment.

Screenshots attached showing the process and results.
