The option for the Columns regarding the Archive pages including the Shop & Category pages are globally set under the Dashboard > Theme Settings > Product archive > Product grid: https://xtemos.com/wp-content/uploads/2020/09/products-grid-wd-7.jpg
So, if they are appearing differently on your Site even though selected correctly under the Theme Settings then it needs to be looked upon on your Site. Kindly, please share your Site WP-ADMIN Login details in the Private Content field so that we can check this concern on your Site and help you out accordingly.
