[GAMEPLAY] Zac's W (Unstable Matter) AP Ratio Not Showing

So in Patch 9.11 Zac's R got reverted, but also his W (Unstable Matter) got a conversion of 100 AP = 2% Max Health damage.

While playing him I noticed that there's absolutely nothing showing next to his W damage, there's no conversion for AP and it just shows the flat amount. So is his W not buffed even though the patch notes say it is? Or is it simply a coding issue where the conversion wasn't put into the ability description?

Thought I should let you guys know, while it's not a hard conversion rate to memorize, it leaves me wondering if the buff actually went through or if the patch notes might be wrong?
