Problem with breakpoint visualizations

Hi, I was testing Webflow, and I think I have found a bug:

I was creating a big full screen menu that will be hide in its initial state, and it will be only visible on mobile (and when triggered).

But here is the problem, if I select “mobile only”:

It seems that it doesn’t care about the display: none that I gave before.

(as you can see, the black panel it still visibile).

What can I do? Is it a known bug or am I missing something?

Can you please share your project’s public link so it’s easier to understand your issue?
