Vertical Slide with Center mode not working

[krzwt]

The vertical slider with center mode set to true does not work when trying to display more than 3 slides. We have used 12 slideshows, and they start from the top, appearing as shown in this screenshot.

We have used the below code

$('.slider=name').slick({
        autoplay: false,
    centerMode: true,
    infinite: true,
    rows: 0,
    arrows:false,
    slidesToShow: 13,
    vertical: true,
    verticalSwiping: true,
    centerPadding: '0',
});
