Exported navigation menu behaving unexpectedly - it appears on scroll rather than on click

On Webflow my navigation menu works perfectly - after clicking the hamburger menu in the top right hand corner the navigation menu drops down, and this work on all pages. After I export the site and click the hamburger menu (on any page) nothing happens, but once I scroll either up or down the navigation menu will appear. I’ve looked thoroughly through the webflow and can’t see what might be causing this, does anyone have any suggestions?

Here is my site Read-Only: Webflow - Copy of Curve Club Website
