Goblin Trapper shooter

Valera 111 I made a Goblin Trapper into a ranged unit, but when he throws stones, the snare gets stuck in the air. Is there a way to fix this? I also made a Trapper into a ranged unit. He throws snares with his ability and shoots with the animation of a regular attack: a swing with the snare and then he throws a stone, I gave him 8 shots.
