Materialization tables created by DLT include these columns to process expectations but they might not propagate to Unity Catalog representations such as views or schema-level metadata unless explicitly set up for such lineage or column-level exposure
A limitation or feature gap might be causing these columns to appear in the Delta table produced by DLT but not in the Unity Catalog, as Unity Catalog focuses on governance and schema definitions rather than operational details of DLT pipelines.
If needing those columns in Unity Catalog for governance or operational tracking, please consult Databricks support to determine if there's a configuration for such propagation.
