User deleted in Person Management but profile still active in Security Console

Summary:

We have a couple of cases in Fusion where the user profile in Person Management was deleted using the Cancel Work Relationship. But this is not syncing with the Security Console. The user profile in Security Console is still active. We have run the Update and Synchronize Key Words processes but the sync is not being effected.

Content (required):

Is there any specific process that needs to be run to synchronize the changes that are made in the Work Relationship (or person management) with the Security Console?

Also, is there any method which we can use to prevent this from happening in future?
