Steps to Reproduce:
1. Open attached project
2. Install Window > Package Manager > Lightweight RP
3. Project > Assets > right-click > Rendering > Lightweight Render Pipeline > Pipeline Asset
4. Project > Assets > right-click > Rendering > Lightweight Render Pipeline > 2D Renderer
5. Assign UniversalRenderPipelineAsset to Edit > Project Settings > Graphics > SRP Settings
6. Assign New 2D Renderer Data to Project > UniversalRenderPipelineAsset > Inspector > General > RendererList
7. Change value of Global Light 2D > Inspector > Light 2D > Light Order to 5
8. Click on Hierarchy > GlobalLight2D > Inspector > Prefab > Overrides > Apply All

Expected result: Changes applied to the prefab
