Hi there,

After hours checking on your site, it seems that we still cant found out the culprit for this issues yet

We would suggested you to re-upload those image again or remove those blocks and re-add it again in order to fix that as i tried to implement those on exact copy of your blog post as you can see here https://www.kal.net.au/news/RobinaFirst/robina-first-winter2017-4.html it is working properly.

By the way, i will extended this to our developer and they will continue checking this issues. Thanks for your understanding
