Sync from CRM - contact changed email address

Sync from CRM - contact changed email address

I've got a contact in CRM that changed his email address (the old email address is now in the field "Secondary Email").  

Now when I do a sync from CRM to Campaigns, the old record in Campaigns isn't updated anymore, but no new record is created either.

In Zoho CRM the contact id is 1037184000000227359 if you can look.
