Problems When Adding Schema To Site

I'm trying to add Schema to a site for a client by just pasting it into a generic headers and footers plugin.

After installing the code, it is visible on almost every page? I thought schema was just an invisible script to help with local SEO?

I've never done this before, and just wondering what could be causing the problem.

Here's the code-

<div itemscope itemtype="http://schema.org/LocalBusiness">
<a itemprop="url" href="salon504.com"><div itemprop="name"><strong>Salon 504</strong></div>
</a>
<div itemprop="description">Salon 504 is located at 504 Garrison Avenue in Fort Smith Arkansas</div>
<div itemprop="address" itemscope itemtype="http://schema.org/PostalAddress">
<strong>Address : </strong><br><span itemprop="streetAddress">504 Garrison Avenue</span>,<br>
<span itemprop="addressLocality">Fort Smith</span>,<br>
<span itemprop="addressRegion">Arkansas</span> -
<span itemprop="postalCode">72901</span><br>
<span itemprop="addressCountry">United States</span>.<br>
</div>
<strong>Tel : </strong><span itemprop="telephone"><a href="tel:479-308-34448">479-308-34448</a></span><br>
<strong>Email : </strong><span itemprop="email"><a href="mailto:salonfivezero@gmail.com">salonfivezer o@gmail.com</a></span><br>
</div>
