Xils-Lab PolyKB - Loading/Saving presets

Does anyone use Xils-Lab PolyKB3 with Cubase? For me, it doesn’t save and reload PKB3 sounds. Every time I close Cubase and reopen the song, the PKB sound resets to “init”.

Also, should I expect to see the full PKB3 program list in Cubase the way i do with Halion, Prologue, etc? Or do I have to always open PolyKB and select the sound from their menu?
