Description: Audiences that are created in Audience Library show up in Target. This is really nice until you delete the audience from Audience Library after which point it will be gone from Audience Library but still show up in Target UI in the Audience list.
Feature: Please either make it so that the system automatically deletes the audience from both places or provide a button that allows the end user to hide/delete these stale audiences from inside of Target UI. As seeing them with the notification is very cumbersome as it adds unnecessary data to the audience list. This might not be a problem for accounts with just a few audiences however it becomes a real inconvenience for accounts with a lot of audiences. See screen-shot below.
Deleted audiences still show in Target UI:
