My menu suddenly reset to default and the only thing left of my menu customizations is submenu items that are in the couple of default main menu items I use under their original name. I have my user data backup from a few days before it happened that I can install on other devices and everything is fine, but when I try to restore it to Fire Stick the menu is still like this. I tried deleting everything, reinstalling Kodi and my user data but that didn't make any difference. Everything else restore fine, just not the menu.
