Hi,
1/ If you're using the new configuration system for the menus ; that information will be stored directly in Joomla.
Which means that you need to edit the value directly in Joomla or in the Joomla menu table.
If the data is still from the HikaShop table ; you could perform a SQL query in order to empty the right column and let HikaShop use all default values for these menus.
2/ I think you have a custom CSS for the HikaShop backend file.
So you do not have the CSS for the floating menu.
