The cause is the creation of a Column Override [sys_db_column_override] record with an active value in the Display by Ref Override [display_by_ref_override] field.
Workaround
- Deactivate the Display by Ref Override field in the override record.
- Clear the server cache via the following command in the browser console:
javascript: window.open(`/v1/settings/flush-cache?access-token=${s_user.accessToken}`);
