Help GPUparticle2D with black "shade" when in Box container

Godot Version

4.3

Question

Hello,

I am trying to figure out why there is a black “shade” on my GPUParticles2D when I place it inside a BoxContainer. Outside of the box, everything works fine.

The buttons 0, 1, 2 are the scene that contain the GPUparticle2D

I have uploaded a screenshot of my problem.

Thanks for your help!
