Folder in main nav as a link changes font weight

I am using the nueva template (brine family) squarespace version 7.1. I wanted my folder in the header navigation to link to the first page in the list. To do this, i put

1.< a href="mission">About

Under "Navigation Title" under the configure folder settings. It works, in that clicking "about" in the header nav now takes user directly to "/mission"

BUT now the word "About" in the header nav appears slightly lower than the other navigation options. The website is not published yet, but here is what the issue looks like:

The formatting change goes away when i remove the code in the navigation title.Any help would be greatly appreciated!!! Ps: I got the information on how to do the folder navigation title insert here: https://answers.squarespace.com/questions/13008/folder-navigation%3A-top-folder-doesnt-link-to-anything%2C-can-i-get-it-to-or-remove-link-behavior.html

@grandmother you should setup password & share url. Difficult to help without site url.
