There’s just not enough space all the elements, I would say it’s normal.
1. I assume it’s a page hero? If so you could try to reduce the left and right padding for mobile in Header element settings, or reduce the font size for mobile using CSS.
2. Reduce the font size of site title at Customizing > Typography > Header > Font size for mobile. Or remove the Menu label for hamburger toggle at Customizing > Layout > Primary Navigation > Mobile Menu Label.
