Hi Syeda, thanks for the info. Auto-dedupe rows is not turned on automatically, it was turned on in table settings at a time the table was not running. If you take a look at the Table History (can be found in bottom right of your screen with the clock icon) you can see the rows that were deduplicated. It looks like this import may have happened a few times already.
As for the 25% not progressing, I don't believe the table is currently running. This just shows you the progress of the table, and it includes the export column that has not run yet (it cannot run currently as there are inputs missing) and also includes the enrichment not running on the other rows.
