[Bug - Match History Beta] Kills Reversed on Graph

When checking out the Match History beta, the first thing I did is look at my most recent game, which is here:

http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1439420850/37426628

It was just a simple Intermediate Bot game, with the Human players on Purple side - which seems to be the crux of the problem.

On the graph portion of the report, the Kills appear to be reversed - as you can see, even though the Humans are playing Purple side, the graph reports the majority of kills to be on Blue side.

Furthermore, if you hover over each kill, it attributes all the kills wrongly. Specifically, it attributes the kill to the player in the same champion slot position, but on the other team.

Since that's rather vague and confusing, let's use an example. I was playing Tristana, and I know I got first blood, which is reflected in the chart below the graph. However, when hovering over the kill dot, it says that Kog'Maw killed Nasus, when in actuality I (Tristana) killed Galio. If you look at the champion list at the top of the report, you'll note that Kog'Maw is opposite Tristana, and Nasus is opposite Galio.

A further, more blatant example is the last kill dot of the game: as Tristana, I got a quadrakill. On the graph, however, all four kills are attributed to Kog'Maw, my opposite.

This also appears to affect the map below the graph, and to the right of the chart. Kog'Maw is reported in the statistics to have 8 kills, whereas Tristana is reported to have 17 kills. However, if you click on Kog'Maw's icon, there are 17 dots on the map. Similarly, clicking on Tristana's icon gets you 8 dots on the map.

Looking at other games in Match History, this only appears to happen when Humans are playing Purple side in bot games.
