custom fields not appearing in Edit Post screen

i created a custom post type with three custom fields and was able to add custom posts via the WP dashboard. i just added three new custom fields, all checkboxes. i created a test custom post and the check boxes are checked and listed in the Edit Post screen under CustomPress Fields but they are not listed under Custom Fields. They are listed in the drop down for Add New Custom Field. Why are they not listed under Custom Field like my first three custom fields?

Thanks
