Having trouble adding effects to both eyes, please help!

[Pcam86]

Hey everyone,

So I've been trying to edit my eye colour using video copilots colour vibrance plugin which says to add the effect to an adjustment layer.

Whenever i do this it will only add the colour vibrance effect to one eye. I'm guessing there's something really silly or obvious that I'm doing wrong.

In the adjustment layer I've linked it to the right eye null but can't parent it to the other one so even though I've masked both eyes inside the adjustment layer it still doesn't work.

Please help! 
