How to remove a header from a theme

Hi, it’s probably easier if I link my website -
You see how there’s these headers: Home, about, example, log in and subscribe? I am unable to remove “log in” and “subscribe” from the backend… Do I need to inject some code for this one?

Thanks guys

It seems that the login & subscribe links are hardcoded instead of dynamically rendered by the primary or secondary nav.

As you can see here:

You will have to delete this entire section inside the red box to remove those links.
