Match Hitory Bug - Yorick Damage

So I won a game with Yorick recently. Check out the match history page here: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2149618301/32323134?tab=overview

In particular, notice the Damage to Champions section. A little outlandish but I did super well that game, right?

But then I played another match and fed hard as Yorick: http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/2149688526/32323134?tab=overview

Yet again, check the total damage to champions. Either Yorick is broken op rito pls or this is a match history bug. And seeing as he's getting reworked sometime this year, I'm guessing it's the latter.
