Lottie scroll not sticky on 14inch screen only


I have a scrolling Lottie that was previously working on all screens, however, for a 1080p 14inch laptop screen, it has stopped sticking on screen when scrolled. Instead, it scrolls past the animation. In the screenshot below, the bike is meant to remain on screen as the text appears. I can’t replicate this in the preview mode, or on any other screen size.

I have no idea why it has stopped working and only for this specific screen size.

Any help would be SUPER appreciated!

Thanks so much
