I know virtually nothing about Libre Office, but since its word processor is designed to mimic Word, it wouldn't surprise me. I just posted that link a few minutes ago; have you actually read through the article. It describes exactly the behavior you are seeing.

Just tried some of the stuff the article linked to here http://www.shaunakelly.com/word/styl...ifyastyle.html And it seems to work so thanks! I'm not the most technically minded individual so it did confuse me slightly initially but thanks for the advice!
