How would I get rid of that reflection thing that comes up on the screen from the muzzle flash

As you can see there is a weird orange box reflecting onto the screen about half way. I can’t seem to be able to get rid of it

This effect looks glitched and bad so any help to get rid of it would be much appreciated.

It’s something to do with the way you’re managing the effect.

How is it setup? I’m assuming it’s a particle?

Somehow, it’s getting too close to the camera.
