How to get csv data to import into person token?

Hi there,

I have an email that I need to send that has a custom field that needs to display for each person.  I reviewed the answer on this post: https://nation.marketo.com/t5/Product-Discussions/Creating-Custom-Tokens/m-p/199201#M144936 and went into the admin, and created a custom person token "{{lead.Your field name}}.  

Now, I imported my data, and selected that field name for the import.  I can look at the list and see the data has imported into the correct field, however, when I look at the actual personalization (in the preview), the field is blank.  The default value isn't even showing up (the text I replaced the "edit me" with.

Any idea where I went wrong?

Thanks!
