I didn't tumble to the "External ID" field when we imported our data.  Now I'm trying to add that so I can use the import in CiviMember to import membership dates and such. 

80% of my records have a date of birth and a date of baptism. I set contact matching to First, Last, Birth & Baptism(custom date field).  I set the import matching option to "Fill" - import created new records for every row in the csv.  Tried it again set to "Update" - same deal.

Any advice to make this work?

I did in fact reproduce it.  I created three records using only first, last and birth.  I created the attached file and attempted to run an update import to update the external id field on the three records and I ended up with six records - the three original records and three duplicates that also include the external id.

I'll file an issue.
