I’m running the latest release of WordPress and Graphene. I have been working for a couple days on building a new site and just ran into the most bizarre behavior with the menus. I have a top menu that has 4 pages. The 3rd of the four has 4 additional submenu pages. I go to the menu section of wordpress, I arrange them in the order I want them. I grab and indent the 4 pages that are submenus items. I hit save and it deletes the submenu formatting. Have always done it this way. Not sure why it keeps deleting my submenu and forcing it to the top level.
