How to remove auto generated rows + columns from grids

Hello - When I go to my mobile portrait and landscape views for my site (on the page called “Masjids”), my cards section has auto generated columns which I can’t delete. I would like to delete the rows to only have 2 or 1 so it can display nicer. How do I do this? Thanks
