- Please set in Databricks that it is saved directly to the bronze delta table without performing any aggregation, just 1 to 1, and check if all records are there.

- Please consider using Delta Live Table for ingestion from Event Hub. It will make your live easier regarding monitoring stream, data quality, and performing full refresh when needed.
