Is anyone else aware of a bug with Ahri's passive healing?

Here is a picture of the passive listing no AP scaling. https://gyazo.com/412ad0fb2d2a7f5c32f7c94935ce73fc As you can see, despite having 35 AP, which should give an additional 3.5 health per hit, it still lists +0. This bug continued for the rest of the game.

Yeah, it's bugged.
