SEO - GA code firing twice

[nyuday]

When we load gauge.org, the tag assistant points out that the 'Same web property ID is tracked twice'. This messes with our analytics numbers and needs to be fixed.

It looks like when we load the page, the GA code is fired twice - 1 from GTM and 1 from GA.

Need to place this as close to the opening head tag:

  <!-- Google Tag Manager -->
<script>(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-5C33ML2');</script>
<!-- End Google Tag Manager -->

And this after the opening tag

<!-- Google Tag Manager (noscript) -->
<noscript><iframe src="https://www.googletagmanager.com/ns.html?id=GTM-5C33ML2"
height="0" width="0" style="display:none;visibility:hidden"></iframe></noscript>
<!-- End Google Tag Manager (noscript) -->
