Kalista Rend Tooltip

Remember when Kalista's Rend tool tip told you how much damage each spear did? Whatever happened to that? Why is it gone? I've noticed the Tooltip cleaned up for errors numerous times but I am yet to see the "Each addition spear does an additional XX + (XX) damage" like it used to. And there really isn't all that much to say, I just wanna know where it went and why it's gone.

Please help :o
