Arrows bugging - will not hide on sliders mobile & tablet ver

Hi there! I am trying to get the arrows for my sliders to be hidden for tablet and mobile version. However, when I click on the “Hide arrows at each end” button it glitches and only hides the left arrow sometimes, and then sometimes it does not show the arrows, but it does not allow me to click left or right. Why is it bugging, do I need to contact webflow?

Same problem. Right arrow wouldn’t hide on mobile breakpoint while “Hide arrows at each end” checkbox is enabled.
