1. Please use “after the header” option instead.
I have checked the situation you mentioned but the header will not display two times if “after the header” option is activated.
Please provide your WordPress login information to me, I will investigate it online on your website.
2. It’s possible to have link for the header with this HTML code : <a href="#">Your Link</a>
Please change the value of URL (#) and text(Your Links) based on your desired.
