I have a slick slider with a few images in it but scrolling left doesn't seem to work.

here is my slick slider code:

$('.items_functions').slick({
  infinite: true,
  centerMode: true,
  slidesToShow: 3,
  swipeToSlide: true,
  variableWidth: true,
});

I have infinite scrolling on though when i scroll to the left, I can only scroll 4 images
