Navigation bar disappearing on one page


I have a weird issue I cannot identify on a specific page, my navigation menu suddenly disappears for a few seconds even though it should be same settings on my other pages.

The navigation bar sometimes disappear and only shows after you scroll down on the page. I tried to deactivate the specific animation for our navigation menu…

Could any one take a look?
