Interactive book animation bug

I’m having an issue with this interactive book animation which I cloned from another Webflow site. It is located at the bottom of my homepage. On tablet and mobile it works fine, but on desktop and landscape phone there is a bug. After clicking to go to the next page, the left side is covered every time by the first left page. Preview on tablet to see how it should work. Would appreciate any help on this!
