Shopkeeper Load products settings

Hello, I have a question that I need your help, or if you can’t help me please tell me where I could search.
On my site, when I open this page (example) Vestidos e Macacões Archives - Violet and Ginger it loads 3 rows and it stops on the first image of the fourth row to load more.
Is there a way to define how many rows it loads each time?
Like this it gives the impression to the clients, that there are no more products on the category.

Thanks for any help

Nobody has an idea about it? Please?
