Category Items With ONE Product, Some Link to Product, Some Don't

[toad78]

Joomla 2.5.x
VM: 2.6.12

On this page, there are three items at the top that do not directly link to the ONLY product that is under their category. Whereas the bottom three directly link to their ONLY product. I want the top three to directly link to their only product.

Click on the image links and you will understand my dilemma.

It seems rather odd that the top three won't but the bottom three do. The category details are all the same, so I'm not sure where to go to fix this.

Please do not advise to upgrade as that is not an option at this time. So obviously, if the bottom three are linking correctly but the top three aren't, then I must be missing a simple step somewhere.

Thank you.
