Harmonic Generator passive is not working when Anointed or in general.

I recently got to maps and was able to get the 3 infusions to create this passive on my Amulet.

This is the listed effect: Harmonic Generator
25% increased Critical Hit Chance against Shocked Enemies
40% increased Magnitude of Shock you inflict with Critical Hits

So when I use this skill, I crit an enemy and the shock magnitude does indeed increase by that amount when I crit shock them. But then the ailment goes away immediately. It has a duration of less then half a second and I have no nodes or passives or gear stats that make ailments go away faster. No where on this skill does it say the duration of the ailment is reduced, so I'm assuming this skill is bugged, at least when Anointed on an amulet. It almost feels like I put the improved shock on them from the crit, and then the very next hit makes the entire ailment go away.
