How to fix the appearance of the "up" button?

Question

css

Good time of the day! Faced such a problem, on the page https://ratibor1978.github.io/clinic-paracelsus/ when loading, the slick slider collects pictures and it turns out that the page scrolls, as a result of which the "up" button appears, how to delay loading the button code so that it loaded after the slider collects the pictures, or maybe someone knows how to make this assembly of pictures not visible and the page does not scroll?
