Navigating to the "Stream Associations" by clicking on the icon within the "Outbound Streams" page presents a list of existing Stream Associations if previously configured.

Attempting to modify and existing Stream Association entity by clicking on the edit icon, making the change and then pressing the save icon results in what appears to be an ineffective click where the Stream Association entity remains in edit mode and the save icon also remains.

Clicking "Close" and then clicking on the Associations icon again shows that the requested change was not applied.

The edit appears to be broken for now.
