Quick CSS fix for ecommerce shop on wordpress

Hi all basically I have a little sale button that comes up over the products when an item is on sale (a ecommerce system build on woo commerce and the grid code has been changes so that product buttons line up), on some coded in pages this sits correctly over the images however on pages where I have added a shortcode, it pushes the product doen so the sale button sits over the top. I just need this fixing if possible, both seem to run off the same css but are just displaying differently.
