Question Shader Graph and Exposure issues

So I've been messing around with shader graph for my project and I've come across an interesting problem.
I created a displacement/distortion kinda effect to put infront of a portal and it works fine, except for when I turn up the exposure in my scene for the lighting

The first image shows the effect working but the exposure on my sky volume is set to 0


This second image shows the exposure set to 8 which is where it should be, but now the effect is... well it's glowing.


So I'm wondering if anyone knows what I should add/change about my shader graph to stop this from happening?
This is the graph, real simple
