I would advise backing up your library in MobileSheets under Settings->Backup and Restore->Backup Library, uninstalling MobileSheets, reinstalling it, then restoring your library from the backup. When an icon doesn't show up like that, it's usually an issue with the app launcher on the device, so this should hopefully put things back into a good state, but let me know if it does not.

Thanks!
