Hello I have a list of datasets which disappeared from the editor page see snapshot. However it shows up on the dashboard - also see snapshot below. How do I get the list to show up in the editor section please? Many thanks 
Your looking in page, you should be looking in site structure. Turn on developer tools
Many thanks - I have tried on / off but to no avail. See snapshot below:
Please note the side icons are missing.
I have the same issue including looking at Developer tools but to no avail.
However, I found by adding another section to the page that the dataset then showed up on that new section. Its like it was hiding just off page. I dragged it to where I wanted it and deleted the new section. Not the best way around it but it worked.
