Decursive not showing curses as a mage...

"Decursive supports all classes with cleansing abilities and configures itself automatically, it works straight out of the box, no configuration is required."

But on my mage I can only select "Charm" in the curing order options... all of the rest is greyed out i can't even select curses which is literally what im trying to use the addon "Decursive" for...
