|AlienVault Ticket ID||ENG-104177|
In AlienVault USM Appliance, some custom SIEM views cannot be deleted. For example, if the name of the custom view has a space at the end: "My view ". When deletion is attempted, they will simply move to the bottom of the list of custom views. This issue has been noted in USM Appliance version 5.2 and version 5.3.
This is a known issue and there currently isn't any workaround for how to delete these views.
