Local customizations broke site on upgrade, how to disable?

Ok this is very strange! (to me)

The code that seems to be causing the problem is this?

CSS:

#site-map-dropdown a[href="/users"] {
    display: none;
}

#site-map-dropdown a[href="/about"] {
    display: none;
}

#site-map-dropdown a[href="/faq"] {
    display: none;
}

#site-map-dropdown a[class="keyboard-shortcuts-link"] {
    display: none;
}

Head:

<script type='text/x-handlebars' data-template-name='/connectors/site-map-links/members-as-users'>
    <li><a href="DISCOURSE_SITE/groups/trust_level_2/members" title="Team Flower Members listing" class="members-link">Members List</a></li>
    <li><a href="DISCOURSE_SITE/faq" title="Learn more on using Team Flower Community" class="faq-new-link">How to use Community</a></li>
    <li><a href="http://www.teamflower.org/members-login" title="Manage your Team Flower account" class="team-flower-account-dropdown" target="_blank">Team Flower Account</a></li>
</script>
