Posts not displaying properly

I’ve got a problem that is really confusing me!

If I give a post the same name as a category (for example, if I name a post ‘attacking’ and I have a category also called ‘attacking’) the post displays a list of posts in that category.

But I don’t want it to do that – I want to write something about attacking!

Oddly, I can’t edit the post called ‘attacking’ either. It is, apparently, a category not a post! See this screenshot: [IMG]http://i57.tinypic.com/i5od8j.png[/IMG]

I can’t post a link to the site unfortunately as it isn’t live yet. I realise this might make it hard to answer my question but any tips or suggestions would be much appreciated.
