Some textures now only react to 'WorldEnvironment'

Godot Version

v4.3

Question

Hello everyone.

I am very new to godot and game development in general. I am building a game, following a tutorial for learning purposes.

As i was messing around in the engine (off-tutorial), All of a sudden, without me realizing,
Some textures started reacting to the WorldEnvironment light only.

The textures do not react to any other light at all. If I were to make the WorldEnvironment completely dark, the textures go dark as well.

I’m not sure I understand why some specific textures and not others and why and how this even happened, it was working well before.
I created a new WorldEnvironment and reset some things that might have contributed to this but no luck.

Can anybody help out? Thanks!
