Kayn Icon bug?

When I was testing out kayn in the practice tool, I noticed that the darkin form's ult icon is the same as the shadowassasin (or the unchanged) kayn's icon. The initial ult icon has changed to the darkin one, but the icon for exiting out of the target (second cast of umbral trespass) is still blue, same as the Og or the assasin version. From the trailer video, I know that the ult icons are suppiosed tyo change with the form's selection (obth the inital cast and the second cast) so I am wondering if this was something that was missed or mine is buggy

P.S. the voiceover of kayn's darkin form's ult cast is the same as the old kayn/assasin kayn. Is this ment to be or am I not getting the darkin ult cast voice for some reason?
