diffuse glow looks very different in separate documents

Hello!

I am designing some elements for my website and created a diffuse glow effect that I really liked for one of my icons.

I created this in sort of a brainstorm version of the document and then moved it into its own file.

When I moved it, I noticed the diffuse glow appeared to be very different than from the original document(less pronounced, barely noticeable at all.). Nothing on the diffuse glow appearance settings have changed but there is clearly a difference. (10,5,15 diffuse glow settings for both documents.)

I've attached the images below for you to see. the first one is the original.

What is the reason for this and how do I change whatever settings to make the diffuse glow consistent across documents?

Thank you!
