CQ import is not populating fields in RTC

I am using the CQ Import utility, within the Eclipse client.   I have created an example mapping file and have made the appropriate modifications for my schema.  When I complete the import, the records are created in RTC, but all of the fields are blank.  No data is migrated, except for a note that indicates the record was created from ClearQuest, with the record ID.

I have removed everything from the mapping file except the lines below.  The result is the same, the work item record is created, but is completely empty.  I have exported the CQ record and confirmed that the fields have data.  I have confirmed the target ID in RTC is correct.

What am I missing????

RTC Version: 6.0

ClearQuest version 8.x
