Not seeing all CRM Contact fields

Using CRMOD. I navigate in Eloqua: Settings > Setup > Integration > Configuration > Manage CRM System User > List Fields.  In the new window, I select Contact.  I don’t see all the fields contained in the CRMOD contact record type.  I see lots of the fields, but not all.   I've refreshed the field list numerous times.  I checked in the Get Contacts auto synch and the list of CRM fields isn't the full set.

Any thoughts?
