Error in the navigation bar for tablet view

Hello everyone!

I would highly appreciate in solving a problem I have on my website. I have an error in the visualization of my navigation bar in tablet and smartphone view.
While on the PC view I can see my black bar and menu icon, on tablet view I have a white bar like if the menu is collapsed/open all the time and I can’t solve the problem.

Also do you happen to know ho to invert my menu burger icon with the logo of my company and showing the menu icon on the left, my logo in the center and the “Contact us” button on the right?

Thank you very much guys! Here the link to access: Webflow - ADVISOR-X1
