OCEANWP IMAGE SIZE ISSUE

Hi,

This is my first time posting on a forum for help, I have tried to go through various forums but sadly found no topic relating to my current issue.

I have found that upon customizing the images product category pages, i.e paradisecrystal.co.uk/shop , I am unable to edit the product image on the thumbnail
I have also gone into customize>Woocommerce>Product images and selected uncropped.

I would just like to original image to be shown without it being editted, this could be something so simple but I no good with CCS.

Hoping someone can help me out!
