Item: EMT Elbows 90 

CID: 3523

It's showing as a catalog/product listed item.  The icon to view/edit the catalog/product list is grayed out.  I've copied the item, unchecked Certified/Cataloged.  Still cannot edit the product list.  
Modifying is necessary because the radii for some of the sizes are incorrect and more sizes are needed.
