LeBlanc Clone Does Damage [GAMEPLAY]

During my least ranked game I was playing Veigar and after one fight we were both low of which the enemy LeBlanc sent her clone near me I in return try to kill the clone to earn the 25g I however wasn't able to kill the clone and when the clone's time ran out the clone was able to kill me and although the damage wasn't a lot the damage was enough to give the LeBlanc first blood which off set the game. This kind of incident also had happened about a few months ago where when I was playing jungle LeBlanc for fun my clone died to Gromp and although I had obtained the exp I wasn't able to get the level 2 please fix this issue. Thank You
