I changed the playback template from Halion to Noteperformer. When I now try to enter the NP interface (and it shows on screen as NP), the Halion window opens up, and I can’t access the NP mixer - can anyone explain this weirdness?

I changed the playback template from Halion to Noteperformer. When I now try to enter the NP interface (and it shows on screen as NP), the Halion window opens up, and I can’t access the NP mixer - can anyone explain this weirdness?

It’s a bug.
Could you please go to the VST & MIDI tab and delete every instance of NP or HALion there and then reapply the NP playback template?
