Slider not working so well on Trackpad

HI, I am not sure why the slider works on mouse but need to wait around 2 sec before I can use trackpad to scroll again, it doesn’t have a problem with mouse scroll.

I’ve tried to add the code from here before, but it still doesn’t work well on Trackpad. Change Slide On Scroll Utility - Webflow

Also on mobile, if I want to go back to previous slide, it will slide back but the direction doesn’t change.

Any one has an idea?
