Interaction not work on first load of page

Hello,

I want to create a slide in div when I click on my hamburger menu. I tried using interactions and use the Move animation to slide in. However, the animation does not seem to work well when the page was first loaded. Once I click once, the rest works as expected.

Any way to solve the initial load problem please?

Thanks!
