MIDI Instrument USB connected unuseable in Dorico 5

it is not possible to use my CP88 (USB connected) as Midi Instrument in Dorico 5 now. Dorico 4 playback/input with CP88 is fully functional on my PC. The same project opened in DORICO 5 has no playback, sustained notes on clicked notes (no note off). There is no way to change this. Whats going on, please?
