[PoE2] Tornado Shot with +1 Arrow - Tornadoes disappearing

When using Tornado Shot with a +1 Arrow bow, I'm noticing that one of the Tornadoes ALWAYS disappears after about 1-2 seconds. It can be really frustrating since I'm trying to shoot through one and then it disappears and I have to maneuver around the pack of enemies to aim into the one that stuck around.

Is this intended or a bug? Anyone else experiencing this?
