Interaction/page transition not animating on published site

Need some assistance.

When I publish my site some the interaction doesn’t animate. Have tried in Chrome and Safari but both are the same.

The menu links are supposed to fade out and the vertical line slides out one side of the browser and into the other side of the browser, and then fade up again. But instead it just jumps from page to page. The other interactions work ok so I think I’ve done something wrong?
