Can someone tell me why some attribute images are four per row (should be this way) but one product has them in a column?

Right:
http://www eccobella com/cosmetics/cosmetics/long-lasting-lip-crayon (need to remove spaces in url)

Wrong:
http://www eccobella com/cosmetics/cosmetics/vitamin-e-lip-smoothers (need to remove spaces in url)

In the past, I've edited /includes/modules/attributes.php to remove <br class="clearBoth" /> but since most image atributes display correctly, this does not seem to be the issue. In fact, if I remove it new problems occur with attribute images displaying weird.
