Great problem with the ultimate version

I have a problem with the update, I had an older version of the plugin, and had a extensive catalog of products, before it was configured with 5 products per row, and suddenly, when I updated the plugin .. All widths products changed, they became larger and a few rows had 2 products in other 3 … What can I do to return to the previous grid ???
