HDR project visually stopping my shaders?

Hi there,

This might be hard to explain so bear with me for a few seconds.

I made a shader using the shader graph in Unity and for some reason, part of the shader gets "covered up " by the project. Now I came to this conclusion by turning on/off the Directional light, Default Post-process, Scene Post-process and the rendering settings that were provided in the scene when I created this project.

Why is this happening and what can I do to fix it? I have generated the lighting and updated Core RP Library and High Definition RP to the newest version (6.9.2)

I have attached an image for reference.

 

UPDATE : I pinpointed the settings causing this issue. If I toggle off the directional light and both the "Volume (Script)" and "Static Lighting Sky (Script)" the shader actually works like it was shown in the material preview.
