Contingency plan not working right?

So her rank 7 helix mut is a lv 6 option that is supposed to make her phase gate come off cd when her shield breaks. Now from what I know it works like a Nova Shield in borderlands (which btws it dose not say on the helix and it really should) Now what this means is your shield has to fully regen after using this effect to allow her to break the cd again. Thing is I do that and the cd dose not break some times. After it triggering do you need to also do one legit cool down? If so the skill is no where near as good as it says.

I have been wandering about the same thing. Today I entered a fight with full health and shields. A moment later I was at 44 health and Phasegate was still on cooldown. I died. Please fix.
