Why is my search icon not working on the sticky header?

Whenever i scroll down and try click the search icon on my sticky header, it just glitches and doesn't open.

I imagine this probably has to do with a plugin but possibly styles. Do you have any plugins you use for your header? This would be one of those things we need to take a look at ourselves as it could be many things from styles to JavaScript logic. Can you share your URL? If your site is not live you can also share the password if it has one.

I am having trouble replicating the problem. It seems to be working fine. I tested it using both Safari and Chrome.
