Custompress custom fields not showing in Ultimate CSV Importer

Hi,

I created custom fields and associated them with a custom post type. I have the WP Ultimate CSV Importer and I am trying to match the fields in the csv file with the custom fields I created. There is an option in the importer plugin to select the custom post type, and then beneath that it allows you to map the csv columns to the proper fields. The fields are listed in a select box, and I see all of the custom fields except the ones I created.

When we created the custom fields we did check the box to expose these fields to plugins.

We're not sure what we should check to find out why the fields are not showing in the drop down list.

Thanks!
