Taxonomy category page not displaying more than one item

Each taxonomy term page is only displaying one item per term.
For example if i have 3 pages assigned to the term 'foo' when i visit the taxonomy page for foo only one of these pages will be displayed under the term.
Also, if i click on the feed icon for the term, the feed will generate the full list of pages in the XML - with all 3 pages in the feed.
In the view admin settings, if i check the preview for the view through the interface it will also generate the correct display with all pages inside the preview of the page view.
It is only when the page is generated that it will simply just display only one item.
