On the ESO zone constants page of the spreadsheet, the dread cellar is not marked as a dungeon.
This seems to be due to it being called Dread Cellar on the Dungeon constants page, but The Dread Cellar on the zone page.
A similar issue occurs with Rockgrove, due to it not appearing at all on the Dungeon constants page. I'm assuming this is not intended and is due to some reason unknown to me because all other trials appear in the data.
