Ensure that all of the extensions for the attributes are correct on the Fields tab of the import.  Because some attributes have comments and some do not, the extensions can be incorrect.

For example:

1. Deceased has a category and description.  Both should have an extension of 00.

2. Other Last Name has a category, description and comments.  All three should have an extension of 01.

3. PeopleFinder has category, description and comments.  All three should have an extension of 02.


Note: On the Fields tab, also ensure that all fields are mapped properly.
