rows not working in slick?

Question

Layout

the code

$('.popular-brands__slider').slick({
      rows: 1,
      slidesToShow: 8,
      lazyLoad: 'ondemand',
      slidesToScroll: 3,
      dots: true,
      arrows: true,
      responsive: [
        {
          breakpoint: 993,
          settings: {
            slidesToShow: 5,
          }
        },
        {
          breakpoint: 741,
          settings: {
            rows:2,
            slidesPerRow:2
          }
        }
      ]
    });

at 740 the slider just disappears
