Remove style overrides

A plus sign next to the style name in the Character Styles panel or the Paragraph Styles panel indicates that there are overrides to the style. An override is any formatting that doesn’t match the attributes defined by the style. There are several ways to remove style overrides:

To clear overrides and return text to the appearance defined by the style, reapply the same style or choose Clear Overrides from the panel menu.
To clear overrides when applying a different style, Alt-click (Windows) or Option-click (Mac OS) the style name.
To redefine the style and maintain the current appearance of the text, select at least one character of the text and choose the Redefine Style command from the panel menu.
If you use styles to maintain consistent formatting, you should probably avoid overrides. If you’re formatting quick, one-time-only text, these overrides pose no problem.
