Configure category page, product items

[Doris@]

Hi, I'm using prestashop 1.7 Firetech 

https://preview.webibazaar.com/137

Somehow i can't fix the list items display on the category ( subcategory ) pages.

Category pages display 4 items per row, Under the items i get these white blocks that i can't figure out how to remove.

I've tried to delete, re install the theme, files, etc

If anyone is so kind please help me with

1 . Fixing this issue

2. Helping me configure the theme so the items on the category and subcategory pages display like in the trending box {pic attached"} ( 3 items per row with more characters in the item title etc ) .

Any help is appreciated. Thanks
