Halion Sound List empty


when I go to “play” and open the Halion Window, to change the Sound of an Instrument, the Result-Lists are empty.
In my early version of Dorico it was possible to select another sound from the list. What is wrong? What can I do to get e.g. different violins?

Thanks in Advance
