Top of arrows cut off on mobile safari ios 15

Using Ultimate Carousel for WPBakery. Desktop is working just fine. When viewing on mobile safari ios 15, the tops of the arrows cut off when pressing the arrow. The arrow initially looks fine, but when pressed, the top half cuts off and disappears. Happens to both left and right arrows. I don’t think it’s an issue specific to my site as I see the same behavior when visiting the developer website and previewing their demo. Any fixes?
