A family of Microsoft word processing software products for creating web, email, and print documents.
Since you see numbering even in the comments, it is possible that someone inadvertently added numbering to the Normal style, which would be inherited by most other styles in Word. Open the Modify Style dialog box for the Normal style, click the Format drop down and choose Numbering. Click the "None" preview picture (even if it already appears to be selected) and click OK repeatedly to confirm the settings.
To fix strange things in the numbered headings, you can try setting up the numbering again.
Also, make sure that "Automatically update document styles" is NOT selected in the Templates and Add-Ins dialog box. To display that dialog, click Document Template on the Developer tab. (To see that tab on the ribbon, go to File | Options | Customize Ribbon and click to select the check box next to "Developer.")
