"Bowling Bash" is bugged

[Static]

The skill "Bowling Bash" is bugged... It seems to always hit twice although it shouldnt if there no one to hit... Cause everytime Cucu hits me with it i take double damage wich i shouldnt unless i hit another player during the push back.

Here's part of description of the skill that i find proves my point:
Bowling Bash will knock a target backward, causing it to inflict damage if it collides into other enemies.

Anyways, point is i wanna know i you could fix this problem.

Thanks for your time
