Navigation is hidden

My website navigation (below the flower icon on the top-left-hand side of the page). I’ve set the display property to “show” on all the various breakpoints. The navigation appears when I publish the website, but then is hidden when I look at the site in my web browser.

I’m sure it’s a simple fix, but it’s been driving me crazy. Any help you could provide would be most appreciated.
