DLT streaming table showing more "Written records" than its actually writing to table

Hi!

I have a DLT setup streaming data from incoming parquet files, into bronze, silver and gold tables. There is a strange bug where in the Graph gui, the number of written records for the gold streaming-table is far greater than the actual data that is written to it. I'm doing a downsampling operation on the timeseries data (for testing) when streaming to the gold table. (1 minute intervals)

Also: I wonder if there's anything wrong with how i give Auto Loader the path to the data:

data_path = "/Volumes/fc_lake_catalog/test_external_schema/test_external_volume/2024/*/*"
the parquet files gets written ADLS Gen2 with EventHub in this kind of structure: 2024/08/04/23/59/*.parquet.
