[CLIENT] End game statistic Healing Done is not working

The Match: http://matchhistory.las.leagueoflegends.com/es/#match-details/LA2/265337287/606777?tab=stats

I played an ARAM with Garen, Warmog and Spirit visage. It was a 27 minute game and the statistic healing done was 5301 points.

That number is wrong, I could upload a video from this match to show over 6K HP healed in 1 minute if you need proof.
