Hi Alta, I just came across your post, I had the same problem and found the answer in the installation information here: http://wordpress.org/extend/plugins/gravity-forms-addons/installation/
Basically you need to add the columns you want in the Directory via Gravity Forms.
In the “Entries: [Your Form]“) screen, find the “Edit” link with the pencil icon in the table header. Click it.
Drag the columns you want in your directory onto the “Active Columns” box
Drag the columns you don’t want in your directory onto the “Inactive Columns” box
Click the Save button.
I hope it helps.
