Fix minor CSS/PHP issue on Virtuemart / Joomla

I have a Virtuemart / Joomla website and it works great. I just need help with a CSS issue, the categories on some pages such as: Delivery, Contacts, About Us, they show the categories tabs unaligned I tried to correct it myself and could not find the problem. I used Firefox to Inspect element, and there is a space (when I delete it) the problem corrects but I don't know where to delete it in the files. I am sure it would take a few minutes for the expert to resolve this. Image 1 shows the way it should look (all of the other pages look like this, except the article/content pages as indicated above. Image 2 shows the the pages that are messed up.
