Kai'sa Bug (W ap ratio doesn't appear)

I played some Kai'sa today on my account and I kept checking the AP ratios on the W but in the description box it said it was (0) despite having a Luden's and Gunblade.

I later did some testing in the training mode to see whether or not it was just the AP ratio not appearing or if it was affecting the damage output as well. It seems that it's just a visual bug not displaying the AP for the ability.

For my testing, I level Kai'sa to level 18 with no items first. Then I bought some items and tried her out again seeing if the damage would stay the same. I checked the description box both times and even though it shows that her current ap ratio in the smaller text, it's not applied in the one above it.

Nothing major about this bug, but it kind of irked me since I couldn't see my damage altogether in game when I built some ap on her.

That's it. Have a great week everyone.
