Foundation 5 - Rails 4 css topbar not working - ruby-on-rails

Question

I am having an issue with foundation 5, rails 4.1.0, as per screenshot, links are underlined, search box is off.
I have created a separate dummy rails app with the same spec and don't see the same issue
I've tried without turbolinks, and different topbar configurations.
any ideas where to troubleshoot this?

$(document).foundation();
});

Found that active admin was conflicting. commented out active_admin.css.scss resolved the issue. That put me in the right direction
