The case of the vanishing List items

https://testbed.odysseyshipping.com/

1. If you do a "View Source", you'll see that there are 4 unordered
lists in the footer yet they are not displaying in the browser
(Firefox or IE). Why?

2. Once I do manage to fire out the above, you can see that two middle
borders do not extend the same depth as the first or fourth. This
must be related to the fact that the first and fourth list have two
items each while the second and third only have one item. But my CSS
has the border in each outer DIV. So why is this happening?

CSS as follows:
----------------------
body {
margin: 0;
padding: 0;
font-family: Arial, Helvetica, Verdana, sans-serif;
font-size: small;
background-color: #FFFFFF;
color: #000000;
