Testimonial Carousel / Advanced Slider

I am using Testimonial Carousel for my site. I set a different amount of slides on the screen related to screen width. For desktop – 3 slides at once, for tablet – 2 slides and for the mobile screen it should display one slide at once, and it works perfectly up to width 360px https://prnt.sc/1g94c5d . When the width of a device is smaller than 360 px – then it displays 3 slides at once https://prnt.sc/1g95v7o and it does not look good, can not find how to fix it. So for screens with a width smaller than 360 px it displays the same amount of slides at once as I set for desktop and that is wrong. Also having the same problem by using Advanced Slider. Could you please recommend me how to solve it?
