My understanding is the Category Exclusion Setting only works by excluding the Categories you have selected in the Preferences for Categories Exclusion Site-wide when you have categories set in that Premier Membership service along with the searches to apply it to, and then you run a search of some sort where you have it set to apply to.
If it isn't set to apply to a particular type of search in the top box of the settings page, or there are no stories to be excluded by your settings, you will get a 0 as the number of stories excluded - because none were excluded.
I checked your preferences and everything is working as expected. How many stories are you seeing in the Updates page?
