The Properties Contents tab in Word is blank due to design.
Cause:
Word ONLY displays the documents containing a title or a first line.
Solution:
Specify a document title.
1) Select the 'File' menu and select 'Properties'. (The document Properties dialog box appears.)
2) Click 'Summary' tab.
3) Type a title in the text box.
4) Click 'OK'. (Word copies the title to the Contents tab.)
