Digital Point Ad Positioning 1.3.0b placing ad after first post instead of after viewed post

Hi I installed this plugin yesterday and I've selected the option "Insert Ad After Post" with the following code:

<div class="sectionMain">
<h3 class="subHeading">Advertising</h3>
<div class="secondaryContent" style="text-align: center">

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- PostGuide -->
<ins class="adsbygoogle"
style="display:block"
data-ad-client="ca-pub-xxxxxxxxxxx"
data-ad-slot="xxxxxxxxxxxx"
data-ad-format="auto"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

</div>
</div>

but it's only showing the ad after the first post, instead of the currently viewed post.

Prehaps I don't understand how this is supposed to work, but if you following a link with a specific post in the URL it should show the ad after that post, correct?

Here is an example:

all other options are "no" and all groups can view the ad.

thoughts? help?

Thanks
