Some Ad units don’t show

Hi guys,

I have noticed that not all Ad units show on my page: https://michaelkummer.com/2016/12/01/is-jetpack-photon-bad-for-seo/amp/

In fact, only one ad unit shows below the first paragraph. But I have enabled ads to show above the content and below the content. Those two units (same ad id and slot) are not showing. Do I need different slots for each?

Thanks
Michael
