Using Post Processing Stack 2 with VR

Hello,
Has anyone had any trouble adding the Post Processing to VR?
I've used it quite a bit in previous versions on Unity without any issues.

However using Unity 2019.1 and now having to use the the latest PP Stack 2 (which I've not used before), I'm getting some strange effects using Depth of Field. I've blurred out the scene as much as possible, but as you can see the blur effect is tearing down the middle of each eye.

Testing this, it's not actually a tearing - it's the PPS2 rendering the effect of both eyes layering on top of each left and right camera/picture, the 'tear' being the gap between both eyes.

Has anyone had this before? Or able to reproduce it?
I don't get this with any other PPS2 settings, AO, color grading etc - only depth of field.

Please help, I feel like I wasted so much time trying to resolve this.
Thank you.
