Theme Issue

Hello Could someone help please?

I have chosen a new theme Petite Stories by Superb themes and on the category page the product variations are showing under the title and before the add to cart button, some of my product have many variatoins so this is not looking good. Is there a way to change this so that they are only showing on the individual product pages? Also with this theme they appear as buttons rather than a drop down. Is there a way to change this also?

I have spoken to the developer who cannot help.

Thanks in advance
