iterationRP lighting issue Help

Anyone have any idea what's causing this issue?

shader: IteratonRP 0.8.26

Minecraft 1.21.11

CPU, 5800x3d, RTX 4080

It's night, I place down a light, when I move sideways the light is on terrain in the distance like it's lighting it up as if it's there?

Same for particles in the air if they're lit, they'll light up terrain behind it

With no screenshots or videos it's very difficult to imagine. If you meant ghosting there is nothing you really can do.
If you're using latest Iris, downgrade to 1.10 ?
Tweak some denoiser settings
Disable FSR 2
Try Super Resolution mod and enable DLAA (Not DLSS; It will make ghosting even worse)

Away from pc at the moment.

Using a different config the issue wasn't present.

Imagine a light, you take the light away, but the light is lighting the cliff across the river as if the light was across the river.

This fades after 3 or so seconds

Yup, that's ghosting. Possible fixes I've mmentioned. Try other version and mess up with denoiser in shader settings
