Moving/Replacing wards with 3 up counts as "ward destroyed" in Match history

Found a possible bug in game, however it does not effect game play, just thought I'd let you guys know. I did not buy a single pink or a sweeper in my last game and there was no one with a blue trinket in my last game. However in match history stats it says I destroyed 14 wards. I know for a fact that this cannot be possible as I only killed 1 ward the entire game. I believe that I reached this number of "wards destroyed" by moving wards or replacing wards after having more than 3 wards out. Again this does not effect game play in any way---unless you are someone that really care about that stat :-) here is match history if it would help review, or if you guys don't think its supposed to be that way!
