If your project has a custom template for `UserFormsCheckboxSetField.ss` or `UserFormsOptionSetField.ss`, then you will need to ensure they include `$Top.getValidationAttributesHTML().RAW`. See
This [`UserFormsColumnCleanTask`](api:SilverStripe\UserForms\Task\UserFormsColumnCleanTask) task is used to clear unused columns from EditableFormField database tables.
To run the task, log in as an administrator and go to `https://example.com/dev/tasks/UserFormsColumnCleanTask` in your browser, or run `sake dev/tasks/UserFormsColumnCleanTask` from the command line.
consider installing the [gridfieldqueuedexport](https://github.com/silverstripe/silverstripe-gridfieldqueuedexport) module. It uses [queuedjobs](https://github.com/symbiote/silverstripe-queuedjobs) to export
submissions in the background, providing users with a progress indicator.
