Hi. It will take a lot of time to solve this (You add endless styles, wrappers and ideas to the core-nav). You should not change the layout of the navbar (You add/remove blocks).
Start from zero (look at the core-working nav structure) + remove styles and add normal styles again.
Look at the blue circle (This is the structure - in your code you move elements - add FLEX and so on):
or - add this to freelance category.
