'Recommended'.

This is quite easy to replicate.

- On any Word document, click File-New
- Double-click 'My templates'
- Click the 'Template' radio button
- Double-click the 'Blank document' icon. You now have a completely new document template.
- Open the Styles pane.
- Click the 'Heading 2' style in the Styles pane. The 'Heading 3' style appears in the Styles pane.
- Click the 'Heading 3' style in the Styles pane. The 'Heading 4' style appears in the Styles pane.
- Click the 'Normal' style in the Styles pane. The single carriage return in the document is now of 'Normal' style. Note that 'Heading 3' and 'Heading 4' are still showing in the Styles pane. Note also that there is NO text of style 'Heading 3' or 'Heading 4' in the document.
- Open the Manage Styles dialog box.
- Click the 'Recommend' tab.
- Note that both 'Heading 2' and 'Heading 3' are shown with '(Hide Until Used)' after them in the list box, but both are in black text, rather than grey.
- Select (individually) 'Heading 3' and 'Heading 2' and press the 'Hide until used' pushbutton. Note that they both remain the same - with '(Hide Until Used)' after them in the list box, but still black, not grey.
- Note that 'Heading 4' also has '(Hide Until Used)' after it in the list box, and it's grey.
- Select the 'OK' pushbutton.
- Note that in the Styles pane, 'Heading 2' and 'Heading 3' still show, even though they have '(Hide Until Used)' showing in black in the Recommend tab of the Manage Styles dialog box. Note that 'Heading 4' still shows, even though it has '(Hide Until Used)' showing in grey in the Recommend tab of the Manage Styles dialog box.
