This a Quickbase support ticket.
You should be able to ask them to restore the App from the backup the night before the mistake was made. Then you can manually enter them back into the production App.
If the placeholders were part of a selection in a User-List, and the User-List is a required field and now no one can edit the records that have the missing Placeholder, you can re-select the User or re-enter the deleted Users.
The alternative is to abandon the production App and move the production table data into the restored App.
Neither option sounds like fun if it's a big App.
