Abyssal Tornado Effect BUG

https://www.youtube.com/watch?v=s2ukRXWVnPU

When using the Abyssal Tornado Effect, the Tornado skill occasionally persists on the screen and fails to disappear even after its duration has expired.

I am unsure if this issue is related to the support gems. Below is the list of gems linked to the skill.

Tornado
Swift Affliction II
Catalysing Elements
Considered Casting
Prolonged Duration II
Morgana's Tempest

Hi I also Want to just reply here, and say I am having the same visual bug, and I have noticed it also coincides with elemental effects being picked up by the tornados. My tornados are picking up shocked ground, and when using the MTX, they stay on the map until I enter a new instance.

You can almost make it happen consistently but the shocked ground is the issue.
