Deleting Pool Attributes or Columns
You can delete any Attribute (AKA Column) in your Pool as long as it came from an Upload or API column Import. Head to Pool > Data > Attributes and look for the delete button at the top right.
⚠️ Warning – there is no undo for this
The data in that attribute will be gone forever, so please be careful with this action. Btw, you can't delete screener question columns as those are tied to individual screeners.
