Advanced Match Details bug

May not be a "bug" but it isn't relaying a certain information correctly. And that information is the amount of stealth wards purchased. Like my last game it said I placed 29 wards and purchased 3 vision wards, 2 stealth wards, and destroyed 3 wards. This info is incorrect because I purchased my stealth wards 3 at a time and placed those over my trinket ward the majority of the game and had swapped to a Sweeping Lens someway through. Just figured I'd throw it out there since it has always confused me and now I realize why. It's just not relaying the amount of "stealth wards purchased" correctly.
