This is because your template is surrounding your content with  tags, and within a MW article, paragraphs are to have some margin at the top and the bottom. To prevent this from happening, you just have to delete this linebreak: 
 * class="infoboxcell" style="font-size:110%; border-top: 1px solid #FFFFFF; border-bottom: 1px solid #FFFFFF; background: #FFFFFF"|

 * class="infoboxcell" style="font-size:110%; border-top: 1px solid #FFFFFF; border-bottom: 1px solid #FFFFFF; background: #FFFFFF"|
