App locked nav issue on prototype

Hey Figma Friends -

I have a weird issue I’m having with an app prototype. I have a fixed locked nav on the bottom with a long scrollable page. Below the locked nav there is a box that is clickable. The problem I’m having is that box is being able to be clicked on even though it’s barely visible. So if you click around the locked nav, it will bring you to that page instead of the locked nav link. See quick giphy: Screen capture - 0fabdbf3a97e1877992b5434b308c105 - Gyazo
