### How to redpoduce

Log into your Joomla 3.0 admin dashboard In the top menu, click Content and then click Article Manager In the list of articles on the page, click the article title that you want to toggle the Show Navigation setting for You will see several tabs above the article, click the Article Options tab Find the setting labeled Show Navigation. Set it to "Hide", and then click "Save" in the top left

When I set the "Show Navigation" setting for a specific article to "Hide", I still see the navigational buttons on the page.
