Kayle only dealing 1 magic damage?

Ok, so after going through more than one Kayle thread, I looked at the wikia page and noticed the AoE missing from the description. It's there now, I fixed that, but before that I did a custom game to look at Kayle's in-game kit to make sure everything's still there.

But something strange was happening: Sometimes, while attacking, Kayle would only deal one (1) magic damage to her target with Righteous Fury's active on-hit.

Whether or not this is a damage text glitch, I don't know, because it's very difficult to read a difference in damage (the physical stayed the same), but I'm here reporting it now. It was only the active portion when it occurred, and never the passive.

Anyone else have the same issue?
