Problem with from project imported instrument track


I really like the feature that I now can import tracks from other projects. And that works well with audio tracks but when I import an instrument track from a different project it looses the Midi In-mapping and more worse, I just can listen to recorded events on Solo. If the track isn’t on solo it’s not playing any of the recorded notes!? But I can play notes live to the playback and I hear them…I just saw that it seems to be a problem with Retrologue2. Every other synth has the problem with the midi in mapping but not with the recorded notes…or it’s a VST3 thing…

Any ideas?
