New Products not displaying in one category

[talbot649]

I've been trying to figure out why new products are displayed in all my categories and sub-categories except one. They seem to share the same code, so it's an absolute mystery to me.

 

I'd be grateful for any help - my store homepage is :

 

http://www.hor-i-zon.com/catalog/index.php

 

and the problem category is Security & Storage :

 

http://www.hor-i-zon.com/catalog/index.php?cPath=517

 

Many thanks in advance for taking the time to look at this problem.

I don't suppose anyone has experienced anything like this in the past?
