This is for anybody trying this in 2.80, and just to add to the above was helpful, I was also having trouble rendering the 2nd pivots.
if you go to Object/Mesh Data and go to collections and deselect render instance they render, also I found doing this there was no need to click don't render button in the properties panel. This seems obvious now, but I hope that helps.
It will render, we dont need to disable render from outliner, only dont check on display instancer and Render instancer
i hope it will help you
