Spacing issue on sticky navigation (hide when scrolling down section)

Hi!
I need some help.

I can't figure out how to fix the little menu that appears when scrolling up.
I have activated the sticky option + hide when scrolling down.

The issue is that on tablet view, I see a lot of spacing between my menu items.
- Very little padding on the left for the icon (I would like to add more space to the left)
- A lot of space between menu items
- Search icon goes a line below.

I can not fix it using the Menu Item Height.

Thanks for your support!
Denise
