How to update materials in Configurator Designer?

I have a materials list that was created using the Engineering Workbench for a configurable part. How do I get material/parts changes made in the Engineering Workbench to update in Method Rules of a configuration that I setup in E9 with Configuration Designer?

There is only one revision and I have changed the material list in the Engineering Workbench. I cannot get the changes made in the related Engineering Workbench to update to the Method Rules in the Configuration Designer for the same configurable part.
