The editor page from figure 4 is pictured again, but now the list of Fields is populated with several entries named string1, boolean1, and string2. The Label column is blank. All the checkboxes in the required field are unchecked. The next column has a little icon on each row which look like overlapping dialog boxes. The author has added a red arrow above this column to indicate the icons. The next column has a red X icon for each row.
