Header Disappears and the another navigator also collapsed

I recommend getting in touch with Elementors’s support about this via https://elementor.com/support/ if you have Elementor Pro or https://projectdmc.org/support/plugin/elementor/ if you do not.

Thanks sir actually I made a mistake that was created a header template then I add a condition that shows on entire website and add that template on my pages as well so my global header was disabled now I change the condition now it is cleared.
