Pre-Release Cinderhulk Displayed in Match History

How to see the bug:

1. Play a match and buy the juggernaut enchantment.
2. After the game is over, open the match history.
3. Open the player builds tab, and hover over your machete upgrade with the juggernaut enchantment.
4. The information for the unreleased cinderhulk enchantment will be displayed.

I've attached 2 screenshots. One shows my match history displaying cinderhulk. The other shows my item sets displaying juggernaut. The following is the link to the match history for that game:

It's not that big of a bug. It doesn't seem to affect game play, and cinderhulk should be released this week, so by then the bug will automatically be corrected. But I just thought I'd let you know anyway.

Thanks!
