Preview Import has blank records

Hey there, lovely Drupal community!

I am trying to use the Node Import module to import batches of products for ubercart (2.0 rc7). I'm using Drupal 6.14. My error is that when I get to step 7 of the import wizard, all of the preview records are blank - unless I include one that has an error (and then only that one has information). Check out this screen shot: http://img18.imageshack.us/img18/1733/nodeimport.jpg

I intentionally gave the top product an error to reproduce this issue (as I did with the attached sample .csv file). If I have no products with errors, they all appear without preview details like records 2, 3, 4, etc. at the bottom of the screen shot above. If I go ahead and hit 'next' and import, it says the rows that had no preview information were imported successfully, but doesn't add them to the site: they aren't accessible through content management, store administration, or directly entering the URL.

Other potentially pertinent information:
- The step-by-step wizard works fine otherwise
- The warning relayed in the screen shot may have an impact, but I haven't been able to find any helpful info to address that warning in the advanced help file, on the drupal.org site, or on the magical internets in general.
- The 'Sample Data' at the bottom of steps 4 and 9 look correct.

This issue has prevented me from importing anything. I'd love to use node import, and I would use it consistently to import thousands of products and updates to their information in the future. However if this issue isn't addressed I'll have to do it by hand or find another group of modules that may work. Any help or clues are greatly appreciated!

Thank you, everyone!
