Put your cursor in the paragraph in question. Scroll the Styles list until you see a boxed Style Name. It may be something like "1. Numbered, 14 pt. Bold." In other words, the style name will be a description of the manually applied formatting. Every time you manually apply formatting charactistics, Word creates another new style name. Don't do that. Edit the style formatting from the Styles window instead.
Click the dropdown on the style name and "Select All instances." Repeat for each of the manually applied styles.
