Menú breaks when you change window size

Hi,
It’s my first time using Elementor Pro, and I created a header for this site: [https://kakao.gobbo.biz/])

​

If you use full screen on your browser, it works well. If you shrink it, it responds, but when you go back to full width, the menu breaks. Any idea why it’s happening and how to fix it?

Thanks 🙂
