Menu icons are not working

Hi everyone!

I am working on my page, and it is not being possible to add icons for the menu. For example shop, cart, home, etc. I think it could be a bug, since the section tu add the icons is not working properly.

Here there is a picture

As you can see, the menu is coming out 2 times. If you modify the icon part, the changes are not saved and not loaded. At the same time, if you modify on the down part, it is just modify the part on the top, and the part on the botton keeps with out any changes.

Thanks for your help!
