Problem with slick slider for the second time?

Question

css

I created a slider, but I don’t understand why when I visit the site for 1 time, the slider shows all the content! Page Guys, has anyone made a similar slider like mine? Can you give an example code, otherwise mine does not want to work the first time! Please share ...
I already asked a similar question and seemed to help, but the next day I found the same picture.
I don't understand what's the matter.
