Why the components are set up I have sent everything correctly, I don’t know why it’s not showing up in my Builder CMS. Are you doing an update on the system?

```auto
Builder.registerComponent(Nav, {
  name: "Navigation",
  inputs: [
    {
      name: "UploadLogo",
      type: "file",
      defaultValue: true,
    },
    {
      name: "NavColumns",
      type: "list",
      label: "Columns",
      defaultValue: true,
      itemProps: [
        {
          name: "NavTitle",
          type: "list",
          defaultValue: true,
        },
        {
          name: "NavItem",
          type: "text",
          defaultValue: true,
        },
        {
          name: "NavItem",
          type: "url",
          defaultValue: true,
        },
      ],
    },
  ],
});

```
