Player kill stats on singleplayer world improperly increases.

My stat screen is showing that I was killed four times by a player, but it also shows that I've never killed a player. This is not possible, as I'm the only player on my singleplayer world and thus both stats should increase whenever I kill myself accidentally.

I also don't think that displaying this stat on a singleplayer world is very usefull, as the only player you can kill is yourself.
