Arrows appear below cards or slides

Hello,

I use Hello Elementor theme and I tried Reviews and Slides elements. But their arrows are displayed at the bottom.

I tried to activate and deactivate following exps: Inline Font Icons, Optimized DOM Output, Improved CSS Loading, Upgrade Swiper library and Improved Asset Loading. They was inactive by default. No effect.

Please advise what else can I do to fix these issues.
