Issue with Custom Ad Box

Can’t seem to figure out how to make a Custom Ad Box display Google AdSense code for a Super Leaderboard ad. This code works when pasted into a regular text box in Visual Composer and displays the correct size (970×90):

<script async src=”//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js”></script>
<!– Super Leaderboard –>
<ins class=”adsbygoogle”
style=”display:inline-block;width:970px;height:90px”
data-ad-client=”ca-pub-6690019914503558″
data-ad-slot=”9551254263″></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

However when it’s put in a Custom Ad Box, only ads that are 300×250 will be delivered. Please see a test page at http://www.weddinc.com/?page_id=362. Text box with code is below the slider, Custom Ad Box with same code is below the Content Block. Sorry to bother you, really tried to work it out myself… Happy to provide login if helpful. Thanks!
