Deliberately deleting NPE objects 7.14.1

Hello, I am using alot of "view" NPE objects on pages to create various views into data...when the view is closed or canceled, i delete those NPE's but they still show up in the state of the client.  How do i get rid of NPE's that are no longer needed from the state?

Have been working too long at helpdesks, so let me start with this annoying question: "Can you reproduce this in a project so we can see this behaviour?"

Where do you delete them, in a microflow or in a nanoflow? Nanoflow, I expect.
