The menu has a max width and it looks like the menu items you’ve selected are longer than the menu max width.
There are 2 solutions:
– remove or edit menu items until they fit in the available space
– edit CSS to allow the menu items you’ve selected to fit it. Here you may need my help, and if you give me your LINK I’ll send the exact CSS
After menu fits it, your logo may be too tall and could need a tweak as well. I don’t know for sure until I see the link. I can help with that too if needed.
