I am having exactly this problem. I had my menus nicely set up with customised main menus that were "empty" and then drop down submenus. I created the submenus by sliding them to the right but wanted to chenge the order of some of them. Everything is fine till I hit Save and then all the sub menus I've touched slide over to the left. Is there something I've forgotten since I first set them up or has something changed?
