I mentioned this a few pages back; its because there's a delay between when Barrage is used and when the buff appears and is recognized, and the next ability is already selected by that time. Same things apply to doublecast Windbite, Venomous Bite, and Straight Shot. Try using the attached files. They're in a couple of different folder locations in the /Kupper directory; overwrite the originals. Note that it does set your 'R' key to aoe rotation, and makes a couple of other changes as well.
