Change Movies Date Added to file creation date?

I tried “Plex Dance” where I deleted the movies library and re-added it. When I sort by “Date added” it still does not show the actual file created date and instead continues to show the date the library was scanned instead…

I am trying to figure out what DB field the Plex webUI uses for “date added’ since all the original dates are correct in my database for the other fields.
