Instagram – Double Image

Not sure why, but my Instagram imports are showing two images (same image)

On this Import for example

http://nullmind.com/2017/08/01/the-prowler-gang-at-santa-pod/

Here is an example of the HTML that gets added on the post

<img class="keyring-img" src="http://nullmind.com/wp-content/uploads/2017/08/20479217_524787117853919_6401776925102047232_n-1.jpg" alt="The Prowler gang at Santa Pod" width="640" height="640" />
<p class="instagram-image"><a class="instagram-link" href="https://www.instagram.com/p/BXPyKyAgnfE/"><img class="keyring-img" src="http://nullmind.com/wp-content/uploads/2017/08/20479217_524787117853919_6401776925102047232_n.jpg" alt="The Prowler gang at Santa Pod" width="640" height="640" /></a></p>
<p class="instagram-caption">The Prowler gang at Santa Pod</p>

Any ideas what might be wrong here ?

I see on older imports the first IMG class did not used to be added to the post …

Example

<p class="instagram-image"><a href="https://www.instagram.com/p/9bBGxWSQkQ/" class="instagram-link"><img src="http://nullmind.com/wp-content/uploads/2015/10/12063182_477175672464782_1949616094_n.jpg" width="640" height="640" alt="Smallest merengue ever !" class="keyring-img" /></a></p>
<p class='instagram-caption'>Smallest merengue ever !</p>
