Hidden/VFX Created on Instantiation, VFX Not Working With Hidden Shader

I am very much a beginner when it comes to the VFX graph and this has totally stumped me. This part of the VFX graph is not visible when I instantiate the prefab that it is within. It is visible if the object has been placed before playing and also becomes visible if the VFX graph is disabled then reenabled.

I think the issue is with the shader. When instantiated, the VFX graph uses this Hidden/VFX shader (below) but then removes it when disabled/reenabled (it works when the shader is gone). I do not know how to stop the Hidden/VFX from being created when instantiated. Also, no errors. Any help is greatly appreciated.
