Navbar hide and show on scroll with breadcrumbs

I got a problem with the hide and show of my navbar while page scrolling, I also installed a breadcrumb section and therefore the menu if i want to open it is going up instead of going/flying into the page, hope someone can help and fix this maybe. Thank you so much.
Here is my link to see what i mean, if you click on the burger menu the menu is going up… :(
