How to fix disappearing X in mobile menu and blank dropdown on desktop?

Hello! hoping someone can help fix these problems.

when the hamburger menu is open is the mobile version, the X disappears.

The X button is supposed to be where I put the red X. how can I get it back?

And in the desktop version, the dropdown menu is blank. How can this be fixed?

We have checked for this issue in real system and browserstack but it is working ok. In which system configuration or browser you are checking?
