I have a map that uses a Folder Data Source (with a template file).  The template file has only the headers in it.  I am submitting ONE source file with five rows (five customers).  When I run the map, it tells me 10 records processed.  5 are successfully imported into my custom table (destination) as designed.  The other five generate errors saying Processing failed for data rows matching CUSTNMBR = ‘XXXXX’.  
I don’t know what’s causing it to think there are 10 records.  The map is set to update existing.
