Article shown instead of section page

[anolian]

Hi

We have some section page that are not displaying. Instead, they redirect to one of the articles which should be shown in full on the section page.

If you go here (http://www.11v11.com/internationals/) and click the OFC link you will see a section page working correctly (it shows some text and some links, which are separate articles) and displays the correct section title.

But if you click say the CONMEBOL link you will get redirected to an article - bypassing the section page.

I cannot see any difference between these two sections or the articles.

We do have DBSEO installed but I see this behaviour even if I turn it off.

Can anyone suggest why this might happen please?

Thanks very much, Mike

PS - not sure if this is related, but I notice that the URLs are not using the SEO Alias specified in vBCMS... They used to...
