Hello Lena,
the Config Tools configuration is not created automatically when the SDK project is created, as not everyone uses the Config Tools and it takes some moments to create the configuration (also download data). If you have not created the Config Tools configuration, that's why in the Project properties it is empty.
Config Tools configuration can be created e.g. by clicking on this icon. This will create a configruation and opens a new Perspective with Config Tools views.

Or using the "Quickstart panel":

Regards,
Libor
