The screenshot shows the admin configured classification levels which is a starting setup requirement, but as reviewed there are key steps beyond that point which need to happen:
1)The Campaign Tracking Code base key values need to be captured into actual live Adobe Analytics reports. In other words your unique marketing campaigns or landing pages should be tagged in a manner so that campaign traffic causes custom tracking code values to show in the 'Tracking Code' menu item. Your comment below indicates you have imported classifications against tracking codes which don't exist yet in your reports which means they will never show up because there is no 'live' performance data yet.
Although, when I look under the Campaigns and Tracking Codes classification reports (or any of the reports for that matter) the key codes/information from the classification document I imported does not populate.
See this link for information on setting campaign tracking: https://marketing.adobe.com/resources/help/en_US/sc/implement/campaign.html
2)After tracking code values are live in your reports then you need to follow the classification import process to upload the classification metadata. It sounds like you have done this against tracking codes which have not been set yet via campaign tagging and subsequent variable s.campaign capture.
Best,
