Why does a shader i added, which adds chromatic aberration to my game, affect text labels, and how do I stop it?

Question

I'm relatively new to Godot and to shaders.

I added a shader to my game that has chromatic aberration, it looks pretty cool. But it messes with other text labels that are not its parent or child node, and I don't really understand why that happens.

Here are the screenshots.

Thank you!

You are giving your screen texture and screen cordinates to shader as an input so shader affects you whole screen without looking your node tree. There 2 ways to deal with it.
1-) Replace all "SCREENTEXTURE" with "TEXTURE" and "SCREENUV" with "UV" in your shader and add your shader material one by one to all nodes except for your labels.(easy way)
2-)You can use your screen as a texture with using viewport node and later add your labels above it. Documents explain this well(https://docs.godotengine.org/en/stable/tutorials/shaders/custom_postprocessing.html)(if there is something you don't understand please ask)
