I would like to change the column headings for the products subpanel under accounts.

On the 'Select a File' page I select accounts and then products and hit the select subpanel button.
However when the next page loads I see no section heading. I see nothing. The screen is blank.
I have the select a file button and edit columns buttons on the left and the custom tag section but there is nothing to edit.
If I select edit columns that screen is blank as well.

Does anyone know if this is a bug or am I missing a step(s)? I tried adding a product to an account but that doesn't do anything either. Any help would be greatly appreciated.
