I've created a form but editing it is a bear. Once I click update, continue editing- I then have to add an item (which goes to the bottom) that I have to delete in order to see the blue box around an item so that I know I can edit it. If I remove something and later want to add it back I absolutely cannot reorder things by drag and drop- so I have to delete the entire form and start over. What am I doing wrong? It looks so easy on your video but it won't work for me no matter what I do.
