This system was not actually designed to work with your existing Categories as is, but instead it is designed to allow you to add a keyword to existing categories that you wanted excluded or included. So here is an example of how it would work.
The points exclusion was designed to work with a single word, so right now “Operational” will exclude but that’s it. And again, it was really designed to have you add a word to your categories and not use the existing categories.
