My site will not split categories

Hello,

For some reason the following code shows all the latest categories instead of the one asked for. As you cna see below the name of the category is OnTheShow and the ID is 3. But another category named BillBlog and id 5 is showing up in there as well.

Can anyone tell me why??

Thanks in advance
George
