Presentation Slider – touchpad scrolling errors

Hello,

I am working on a site using your presentation slider and everything looks great. When I scroll from one page to another using the two finger touchpad swipe up/down, the slides don’t always go in the expected direction. I made sure that I’m not triggering any local touchpad actions and I am not swiping left or right. Is this something that can be corrected or will I have to find a new template? It scrolls correctly with mouse and on mobile swipes, just erroring on touchpad. [browser=chrome]
