ProductList in machining

Is there a way to remove duplicate or unused products in the the "ProductList" I copied part operations from a different process file and applied them to a different assembly. The product that came with it is no longer needed, but I cannot get rid of it. 

Hi,
Yes, it can be deleted.

Copying part-operations or programs from other process is not a good idea. There are a couple of better ways to reuse toolpaths. 1. Machining process templates 2. File -> NewFrom..

Thank you, I will change to the method you recommend. For my current files , I still want to clean them up and get rid of the products. How to delete?

Tools/Options/Machining/Operation/When Copying/ - Uncheck 'Duplicate geometry links'
