Post Processing Help Wanted - Night vision disaster

Hello helpful people, I’m having an issue with my night vision post process. I followed this tutorial to make it, and it does work and I can toggle it on and off with a flip flop node, but after I toggle it off it leaves a very warped weird looking sickly almost thermal vision effect that I can’t figure out how to remove. but if i toggle the NV back on the weird thermal vision is removed and replaced with the proper night vision. So I guess what I’m asking is does anyone know how I can make it look like the standard scene rather than the weird thermal when I toggle it off? Thank you in advance.
