How to display product name(rathan than product details- empty) in customize invoice view

Hi there,
I am working on customization of Invoice view. In the selections, there is only category called 'Product Details', however, if I select this, it's empty when displaying it in the Invoice view.
 
The data I want is the product name. Is there a way to add product name to the selection list in customize view? I found this issue in other places as well.
 
Thanks.
