Flatsome Theme> top bar and bottom menu disappears

After updating the flatsome theme, I started having this problem of my top bar and bottom menu disappearing. On load up all is perfect. When i scroll down and then back up, the top bar and bottom menu has disappeared. This only happens on mobile view. I try to fix…im not winning.
