Siren Isle - Persistent Lightning Effect (and sound) after leaving The Storm

I’m about to go insane by the constant lightning sound that is happening after I left The Storm event. I even see some lightning around me when in darker spaces. How do I get rid of this effect?

I’ve already tried to remove all my gear and check all buffs. I’ve also checked my combat log and confirmed that I am NOT taking any damage (other than to my real life ears).
