Categories per row always pushing one category down

[Justin Holstein]

I'm using Virtuemart 2.0.6 and joomla 2.5.4 within the ionosphere rockettheme template.   No matter what number I set the number of categories to, 3 per row, 6 per row, etc., it always does one short and lists the final category of that row below it.  ( see here: http://www.unitedgenetics.com.php53-26.dfw1-2.websitetestlink.com/index.php/products-list ).

So if I list it to 4 categories per row, it puts three on the row and puts the forth below it.  If I list 6 categories per row, it will list 5 in one row and move the last one below it.  How can I fix this

I encountered this a while ago.
The solution in the last post, i think worked.
