scrap yard killer challenge only counted once

Xevuinn

I selected scrap yard killer challenge at level 4(damage 25 generators) and played a match which I kicked generators total 23times, but the end result showed me only 1 counted.

Step 1 : Boot the game

Step 2 : Play as Nightmare in a public match

Step 3 : In-game, damage severl generators

Step 4 : Notice the result doen't counted all the kickings

the video is in korean.
