Website crashing when changing breakpoint with navbar

Hi everybody,

whenever I open my navbar for tablet and under, and then change the breakpoint for desktop and above, the site breaks and looks strange. There are also styles appearing that are extremely old and I’m currently not using on any on my pages.
I recorded a Loom video here:

If you have an idea how to fix it, that would be great!

Thank you!


Here is my site Read-Only: Webflow - Philippe Gnannt - Film Editor

This usually comes from old combo classes sticking to the navbar across breakpoints. Clean up unused classes in the Style Manager, then restyle the nav separately on tablet and desktop to stop the layout from breaking.

Hi Moid, I cleaned up and deleted unused classes beforehand, so that should be fine. Is it the navbar that triggers this? If you could spot the issue and help out in my read-only link, that would be amazing. The old styles appearing back up is also very odd.

Thank you so much!
