2 different Vengeful Winds

I have 2 Vengeful Winds that each have a different tooltip. 1 says I get 10 more stacks with 701% dmg and the other says I get 6 more stacks with no dmg buff. I believe I got 1 from the PTR vendor and the other was a drop, although I’m not sure which is which.

This was on my seasonal monk (getoverhere), I tested to see if the tooltips were correct and as far as I could tell they were. I’ll hold onto both weapons in case you need more info.

I can’t post a link but if you go to imgur a/MRo2yAH you’ll see both weapons.
