The rows and slidesPerRow options do not work in slick. How to fix?

Question

JavaScript

You need to arrange 3 items in 3 rows.
I do it like this:

$('.slider-for').slick({
        slidesToShow: 1,
        slidesToScroll: 1,
        arrows: false,
        dots: false,
        asNavFor: '.slider-nav'
    });
    $('.slider-nav').slick({
        slidesToShow: 9,
        slidesToScroll: 0,
        arrows: false,
        dots: false,
        rows: 3,
        slidesPerRow: 3,
        asNavFor: '.slider-for'
    });

Here is pug:

.col-lg-5
.slider-for
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                .col-lg-7
                  .slider-nav
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')
                    .item
                      img(src='../images/photo-1.png')

And this is what happens if you apply

rows: 3,
 slidesPerRow: 3,

It turns out one item and in it all these slides. And you can't click on them. It is necessary that you can click on them, on each separately.
