Can't add slides to owl-carousel?

Question

Owl Carousel

Hello dear forum users. Recently I came across one very interesting site, I decided to deal with it, but
one small problem arose.
I can’t put two slides, I covered everything .. the only clue that I found is the settings in the owl.carousel.min file ( js/jquery-owl-carousel) and the main.js file (js/main.js) I don’t know whether the author so wanted and put in the variable items: 2, BUT everywhere is 5 (by default). The slides
are in the img/
carousel folder
