Hi @silvio3105 ,
Let's clear this up. @yiqiu.han is referring to the import button inside the library manager, because that's where your STANDARD library is missing. In the top right of the library manager there is a book icon, click it and select import Fusion Team library, then in the dialog that pops up select your STANDARD library.
If ever a library doesn't show up in the library manager that you think should be there, you can go to the icon and manually import it in.
