Summary
When importing a list of Subscribers into a Suppression List, you will set the Status of the Subscriber, should you include a value in the file of something other than Active, the Import will show as successful in the Email Notification but no Subscribers will be added to your Suppression List.

Repro
- Create a Suppression List in your account
- Create a file that contains three columns; SubscriberKey, EmailAddress and Status
- Populate file with Subscriber Key, Email Address, and Status of Unsubscribe
- In your account go to Email Studio > Subscribers > Suppression Lists
- Import the file into the Suppression List
- Include your Email as a notification once it completes
- Review the Subscriber List Import Notification, results show subscriber(s) were inserted
- Review the Suppression List, subscriber(s) with Unsubscribe status are not on the list

This is technically functioning as designed, as you're required to import a Status of Active, but the Email Notification suggests the Import was successful, and records were inserted.

Workaround
Ensure your file has the Status of 'Active' for each Subscriber
