Custom Heatmap Value asset displays unnecessary third column in Subgraphs/Nodes

Steps to reproduce:

1. Create a new Unity 3D URP Project
2. In the Project window, go to Assets → Create → Shader Graph → Custom Heatmap Value
3. Select the asset to view it in the Inspector
4. Expand the Subgraphs and Nodes sections

Actual results: The Inspector displays three columns in each section (Subgraph/Node, Category, plus an extra empty column)

Expected results: Layout should match the content used (i.e two)
