I have found in several places content input tends to disappear randomly.
It happens a lot on the Form view:
The form looks empty…
But the preview tells otherwise!
A bug with 2 layers
- At first, it’s just a problem with synchronization as you see on the previous screen. The form has content, it is just not visible on the edit page.
- The main concern is that, depending on what action you might do next, the fields will indeed get cleared out
That’s what happened to me in the table view, I was adding rows and opening them to fill them with content:
Suddenly the Name of previously edited pages started to disappear… Forever 
I wonder if it has to do with the network being disconnected at times
