Slider began to behave strangely

Today my slick-slider starts to add one space before all `.slick-slide`. Problem is he add rules on class `.slick-track transform: translate3d(450px, 0px, 0px);`
And yesterday it was `.slick-track transform: translate3d(450px, 0px, 0px);`
I didn't change any code in this component. But I have lots of other changes. I roll back all code to yesterday but no luck.
My settings for react-slick are:
`const settings = {
dots: false,
infinite: false,
speed: 300,
slidesToShow: 1,
slidesToScroll: 1,
className: "pins-on-map",
centerPadding: "16px",
centerMode: true,
arrows: false
};`

I can't understand why is this happening. Few last days on intitial loading .slick-track was `transform: translate3d(0px, 0px, 0px);`

Why now add extra 450px?
