I have a window set to alert me when one of my "finishers" is available by making a CD filter and setting single icon to only appear when that spell is usable (kill shot, execute, etc.). But when I change the icon setting from "USED" to "AVAIL" it just shows the icon of a random spell that is available and not on the CD filter. In the picture below it is showing Arcane Torrent.
Could be a bug, or maybe I'm just setting it up wrong.
Thanks!
