Thanks for your Read-Only Share link.
Looking at the Navbar Symbol you are using, it appears that you have modified some of the elements that come preconfigured with Webflow’s Navbar component.
In my experience, I have found that making changes to the component can produce unexpected results and can be very difficult to isolate the exact cause.
It can take a long time and effort isolating the cause that can take away valuable time from progressing your project. In this case, I would suggest recreating the Navbar using Webflow’s Navbar Component and adjust the settings for the Hamburger Menu to only display on Mobile. (As you had previously done)
Let us know if you still experience issues after creating a new Navbar and we can have another look.
Hope that helps,
