2D Light Textures Clashing - I have it on Mix mode!

Godot Version

v4.2.1.stable.official.b09f793f5

Question

I want to have them blend without adding intensity when light sources overlap. They almost do - Not sure if it is my texture that I made but you can see the black border in the screen shot below overlap.

If anyone comes across this, found a guy who recently uploaded a video on how to do this. Custom Lighting System in Godot.
