I have an xml that was created with the online editor.
I then copied and pasted this to a new file. When I had issues in the code, I copied and pasted back into the online editor and the items after the checkbox lost their position and data.

If you move the Checkbox below the last item, the dislay is now correct when you load in the editor.
