I edit science journal papers in Word 365 where I need to apply a certain set of styles. Recently, the style pane is listing many character and paragraph styles in addition to the style sheet I specify. In Style Pane Options, I set Styles to Show as "In current document" and only Paragraph Level Formatting, but it makes no difference. However, in Manage Styles, when I use Import/Export to open Organizer, only the correct styles are listed as the styles in the document.

This means I have to take a lot of time to scroll up and down the style pane to select only my styles.

I've repaired the documents I've worked on; no change. I've reinstalled Office 365; no change.

Is there some setting I can use (other than Style Pane Options) to list only the styles in the style sheet I apply to the document?
